MADWIFI: Multimode Atheros Driver for WiFi on Linux (VAP branch)
================================================================
* Copyright (c) 2002-2005 Sam Leffler. All rights reserved.
Read the file COPYRIGHT for the complete copyright.
Requirements
------------
- Configured kernel sources of the target kernel. Some Linux
distributions provide headers, makefiles and configuration data - it
should suffice.
- Wireless Extensions support (14 or later, 17 preferred) - option
CONFIG_NET_RADIO in kernel .config file.
- Sysctl support - option CONFIG_SYSCTL in kernel .config file.
- Crypto API support - option CONFIG_CRYPTO in kernel .config file (AES
support is used if present, otherwise the AES-CCMP cipher module falls
back to a private implementation).
- gcc of same version that was used to compile the kernel. At least
make sure that the first two version numbers or the compiler are the
same (e.g. it's OK to use gcc 3.4.6 to compile MadWifi if the kernel
was compiled by gcc 3.4.2). Ignoring this rule will cause "Invalid
module format" errors during module load.
Linux 2.4.x kernels starting with 2.4.22 and 2.6 kernels should work
without problems. Due to quick pace of Linux development, there is no
way compatibility with the future 2.6 kernels can be ensured. However,
the latest 2.6 kernel at the time of the release should be expected to
work.
Automatic module loading support (CONFIG_KMOD) is recommended; otherwise,
care will have to be taken to manually load needed modules.
Building the driver
-------------------
The driver is built using the Linux kernel build mechanism. This means
you must have some part of the kernel source distribution installed on
the machine where you want to build the driver. In particular, the
kernel include files, makefiles, build scripts and configuration must be
available.
This will be present if you built your kernel from source. Otherwise
you may need to install an additional kernel development package from
your distribution that would match your kernel. For example, the
development package for the default kernel is called linux-headers on
Debian and kernel-devel on Fedora Core. Installing a package with full
kernel sources should not be generally necessary.
Note: in the following examples "$" stands for your system prompt;
you're not expected to type that as part of the actual command. "#"
stands for the command prompt when the commands must be executed by
root.
Most people can just type:
$ make
in the top-level MadWifi source directory to build all the modules for
the currently running system.
You MUST do a "make clean" before compiling for a different version of
Linux, e.g. building for 2.6 after building for 2.4.
If you want to compile MadWifi for a different kernel, you need to
specify the location of the kernel build tree, e.g.:
$ make KERNELPATH=/usr/src/linux-2.6.3
Note that you can also specify this path by setting an environment
variable; e.g.
$ export KERNELPATH=/usr/src/linux-2.6.3
$ make
If the kernel was built outside the source directory, KERNELPATH should
point to the output directory where .config is located, not to the
sources.
MadWifi currently provides four different rate control algorithms,
ONOE, AMRR, SAMPLE and MINSTREL. SAMPLE and MINSTREL are both very
advanced, but MINSTREL is quite new. Consequently, SAMPLE is used by
default. In order to make MadWifi use e.g. AMRR instead, you have to
specify that as the module parameter e.g.
# modprobe ath_pci ratectl=amrr
NOTE: Changing the rate control is only required (and recommended) for
users who want to setup an access point using MadWifi in difficult
(e.g. lossy) environments and who know what they are doing.
This distribution includes support for a variety of target platforms.
Because of the binary nature of the HAL not all platforms are supported
(the list grows as time permits). The supported target platforms can be
found with:
$ ls hal/public/*.inc
A target specifies the CPU architecture, byte order (unless implied by
the CPU), and the ABI/file format. For most popular platforms, the
build system will find the appropriate files. When cross-compiling or
compiling for less common platforms, the target platform may need to be
specified using the TARGET variable, e.g:
$ make TARGET=armv4-le-elf
Consult the contents of the .inc file to find out what the target
platform is and what toolchain was used to build the HAL object module.
Beware of mixing toolchains; some target platforms require that the HAL
and driver be built with the same toolchain (i.e. compiler, assembler,
and linker) and the same compiler flags. If you get warnings about
incompatible compiler flags, chances are that you are compiling for a
wrong target or using an incompatible compiler.
Cross-compiling
---------------
The build system is designed to support cross-compiling without any
modification to the distribution files. It should be sufficient to
specify any parameters on the make command line.
In most cases, only KERNELPATH and CROSS_COMPILE need to be defined.
CROSS_COMPILE is the prefix for cross-compiling tools. For instance, if
the cross compiler is called arm-linux-gcc, set CROSS_COMPILE to
"arm-linux-":
$ make KERNELPATH=/usr/src/linux-arm CROSS_COMPILE=arm-linux-
The build system determines ARCH and TARGET based on the .config file in
the Linux build tree. TARGET still may need to be provided on the
command line some uncommon systems. If ARCH is determined incorrectly,
please report it.
If the compiler needs additional flags to compile userspace binaries,
you can redefine CC to include those flags.
When installing MadWifi, set DESTDIR to the root of the target
filesystem, so that the cross-compiled binaries don't overwrite the
native ones.
Loading the modules
-------------------
Building the software will generate numerous loadable modules:
ath_pci Atheros driver for PCI/Cardbus devices
ath_hal Atheros HAL
wlan 802.11 support layer
wlan_wep WEP cipher support
wlan_tkip TKIP cipher support
wlan_ccmp AES-CCMP cipher support
wlan_xauth external authenticator
wlan_acl MAC ACL support for AP operation
wlan_scan_ap AP scanning support
wlan_scan_sta station scanning support
ath_rate_onoe ONOE rate control
ath_rate_amrr AMRR rate control
ath_rate_sample SAMPLE rate control
The ath_pci module must be loaded either manually or by the system, e.g.
through the hotplug or card manager support. The remaining modules are
loaded automatically as needed, so after doing a "make install" you only
need to run following:
# modprobe ath_pci
For automatic module loading you may need to modify your system's
configuration files so the necessary modules are loaded when an Atheros
device is recognized. The exact procedure varies from system to system.
There are module parameters available to fit your needs, e.g. you can
set the countrycode manually if your card's EEPROM does not contain the
correct one for your location. See
http://www.unicode.org/onlinedat/countries.html to find your code.
To activate German frequencies you would specify:
# modprobe ath_pci countrycode=276
To see all available module parameters type:
$ modinfo ath_pci
Integrating into the kernel sources
-----------------------------------
It is also possible to patch Linux kernel sources to integrate MadWifi
directly into the kernel tree. This allows building MadWifi as part of
the kernel. This could be useful for embedded systems that don't
support loadable modules. Please refer to patch-kernel/README for
details.
Further information
-------------------
Further information on how to work with the driver can be found in the
file README. In addition, the project's wiki has a lot of valuable
information:

Introduction
------------
This software contains a Linux kernel driver for Atheros-based Wireless
LAN devices. The driver supports station, AP, ad-hoc, and monitor modes
of operation. The Atheros driver depends on a device-independent
implementation of the 802.11 protocols that originated in the BSD
community (NetBSD in particular).
The driver functions as a normal network device and uses the Wireless
Extensions API. As such normal Linux tools can and should be used with
it. Where the wireless extensions are lacking private ioctls have been
added.
There is only one driver included here; it supports PCI, MiniPCI and
Cardbus devices - USB devices are currently not supported by this
driver! The driver can be built as a module or linked directly into the
kernel. Note however that the net80211 layer is device-independent;
there is no reason it cannot be used with any 802.11 device (in fact
this is the case on BSD systems).
This software is broken into multiple modules. The Atheros-specific
device support is found in the ath_pci module; it should be loaded when
an Atheros wireless device is recognized. The ath_pci module requires
an additional device specific module, ath_hal, which is described more
below. In addition the driver requires the wlan module which contains
the 802.11 state machine, protocol support, and other device-independent
support needed by any 802.11 device. This code is derived from work
that first appeared in NetBSD and then FreeBSD. The wlan module may
also force the loading of additional modules for crypto support
(wlan_wep, wlan_tkip, wlan_ccmp, etc.), for MAC-based ACL support
(wlan_acl), and for 802.1x authenticator support (wlan_auth,
wlan_radius). The latter modules are only used when operating as an AP.
The crypto modules are loaded when keys of that type are created.
The ath_hal module contains the Atheros Hardware Access Layer (HAL).
This code manages much of the chip-specific operation of the driver.
The HAL is provided in a binary-only form in order to comply with FCC
regulations. In particular, a radio transmitter can only be operated at
power levels and on frequency channels for which it is approved. The
FCC requires that a software-defined radio cannot be configured by the
user to operate outside the approved power levels and frequency
channels. This makes it difficult to open-source code that enforces
limits on the power levels, frequency channels and other parameters of
the radio transmitter. See
http://ftp.fcc.gov/Bureaus/Engineering_Technology/Orders/2001/fcc01264.pdf
for the specific FCC regulation. Because the module is provided in a
binary-only form it is marked "Proprietary"; this means when you load it
you will see messages that your system is now "tainted".
A detailed discussion of the pros and cons of this design can be found
at http://madwifi.org/wiki/HAL
If you wish to use this driver on a platform for which an ath_hal module
is not already provided please contact the author. Note that this is
only necessary for new _architectures_; the HAL is not tied to any
specific version of Linux - in fact the identical HAL binary code is
used unchanged with other operating systems.
Atheros Hardware
----------------
There are currently three "programming generations" of Atheros 802.11
wireless devices (some of these have multiple hardware implementations
but otherwise appear identical to users):
5210 supports 11a only
5211 supports both 11a and 11b
5212 supports 11a, 11b, and 11g
These parts have been incorporated in a variety of retail products
including Cardbus cards from D-Link, Linksys, Netgear, Orinoco, Proxim,
and 3Com; and mini-pci cards from some of these same vendors. In
addition, many laptop vendors use Atheros mini-pci cards for their
built-in wireless support.
For an up-to-date list of cards based on Atheros parts visit:
http://customerproducts.atheros.com/customerproducts
A list of products that have been reported to be supported by MadWifi
can be found here:
http://madwifi.org/wiki/Compatibility
In general, if a device is identified as ``11a only'', it is almost
certain to contain an Atheros 5210 part in it. Most retail a+b products
use the 5211. Many a+b+g combo products use the 5212 though other
vendors have started to offer dual-band support. When in doubt, check
the PCI vendor ID with a tool like lspci, the Atheros vendor ID is
0x168c; e.g.
00:13.0 Ethernet controller: Unknown device 168c:0012 (rev 01)
but beware that some vendors use alternate vendor IDs (e.g 3Com, IBM).
The file hal/ah_devid.h has a list of known PCI IDs.
Building the driver
-------------------
The procedure to build the driver is described in the file INSTALL.
Using the driver
----------------
The driver should support any Atheros-based Cardbus or PCI device. This
version of the driver is managed and controlled by the usual Linux tools
(ifconfig, iwconfig, iwpriv) plus the wlanconfig tool, which is included
with the driver in the tools directory and gets installed on your system
with make install.
First, run "modprobe ath_pci" or the equivalent using "insmod". When
the driver is successfully loaded it creates two devices, named "wifi0"
and "ath0". The output from iwconfig should look like this:
lo no wireless extensions.
wifi0 no wireless extensions.
ath0 IEEE 802.11b ESSID:""
Mode:Managed Channel:0 Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power:50 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=0/94 Signal level=-95 dBm Noise level=-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
This driver uses wifi%d only as a placeholder for the physical device,
and will create one wifi device for each wireless NIC in the system.
These wifi devices will reject ifconfig and iwconfig commands. The wifi
interface indicates the existence of a physical MadWifi device, but it
is not of any functional interest other than as the starting point for
VAP creation via wlanconfig (see Virtual AP section below).
By default, an ath%d Managed mode interface is also created. This
device is a "virtual ap" (VAP) of the wifi%d physical device, and is
configurable by the standard networking tools - ifconfig, iwconfig,
iwpriv.
The autocreation function can be manipulated to create any one of the
other supported device types automatically by using the autocreate=mode
option when the ath_pci module is first loaded. The following example
will cause ath%d to be in Master mode:
modprobe ath_pci autocreate=ap
Autocreation can be disabled:
modprobe ath_pci autocreate=none
Please see the following link for more information:
http://madwifi.org/wiki/UserDocs/autocreate
Virtual APs (VAPs) and wlanconfig
---------------------------------
An interesting feature of MadWifi is Virtual AP (VAP) mode, which allows
the operation of multiple concurrent (virtual) access points, and
concurrent interfaces running in both AP and station mode. To
manipulate VAPs, MadWifi comes with a tool called wlanconfig which is
used to create and destroy VAPS with various different modes.
The following examples assume that the "autocreate=none" option has been
parsed to the module at load time. This allows fine control over
management of VAPs, as the creation of a Managed mode station should be
delayed until all other required VAPs are first created, as only one
sta mode VAP can exist per physical device.
To create an access point, use:
wlanconfig ath0 create wlandev wifi0 wlanmode ap
To create an access point and a station, use:
wlanconfig ath0 create wlandev wifi0 wlanmode ap
wlanconfig ath1 create wlandev wifi0 wlanmode sta nosbeacon
To create APs that share a single MAC address, use the -bssid flag when
creating the VAPs:
wlanconfig ath0 create wlandev wifi0 wlanmode ap -bssid
wlanconfig ath1 create wlandev wifi0 wlanmode ap -bssid
Finally, to destroy a VAP, issue the command:
wlanconfig ath0 destroy
For more information about Virtual APs, please refer to the users-guide
document distributed with the MadWifi source code.
For more information about wlanconfig, see its manpage, it is installed
when you run "make install".
Operating Mode
--------------
If you have a multi-mode card, use one of the following commands to lock
the operating mode to one of 11a, 11b, or 11g:
iwpriv ath0 mode 1 lock operation to 11a only
iwpriv ath0 mode 2 lock operation to 11b only
iwpriv ath0 mode 3 lock operation to 11g only
iwpriv ath0 mode 0 autoselect from 11a/b/g (default)
Debugging
---------
There are some debugging mechanisms for the curious/masochistic:
sysctl -w dev.ath.debug=0xXXX enable console msgs from the driver
sysctl -w net.wlan0.debug=0xYYY enable console msgs from the wlan module
The values specified for 0XXX and 0xYYY are bit masks that enable
debugging in various parts of each module. For the wlan module these
values are found in the file net80211/ieee80211_var.h (search for MSG_).
For the ath driver look in ath/if_ath.c (search for ATH_DEBUG). Beware
that enabling some debugging msgs can affect the operation of the
software by slowing it down too much.
A more comfortable way to manipulate the debug settings is to make use
of athdebug and 80211debug tools. Call them with the parameter "-h" to
learn how they are used, or refer to the appropriate man pages.
In addition the programs tools/athstats and tools/80211stats can be very
useful in understanding what is going on. In particular, something like
athstats 1
will give a running display of the most interesting statistics sampled
every 1 second. Running athstats without any options will display a
summary of all non-zero statistics from the time the driver was loaded.
By default the ath0 device is used; to override this use the -i option.
A wiki page describes common MadWifi debugging methods here:
http://madwifi.org/wiki/DevDocs/AthDebug
Security/Crypto Support
-----------------------
All Atheros devices implement fixed/shared key WEP in hardware. Newer
Atheros hardware is capable of much more (e.g. AES, TKIP and Michael).
When hardware support is not available for a cipher the net80211 layer
will automatically do the work in software.
WPA/802.11i station operation (aka supplicant) is supported using Jouni
Malinen's wpa_supplicant program. This can be obtained from:
http://hostap.epitest.fi/wpa_supplicant/
wpa_supplicant also supports a wide range of 802.1x EAP methods, either
together with WPA/WPA2 or without; consult the wpa_supplicant
documentation for an up to date list.
MadWifi supports the use of the Wireless Extensions ioctls equal to or
greater than WE18 (linux 2.6.15). When using wpa_supplicant with a
recent linux kernel, it is preferred to use the 'wext' driver backend,
rather than the private MadWifi ioctls. This means that '-D wext'
option should be used with wpa_supplicant when the linux kernel version
is 2.6.15 or above.
NOTE: the in-kernel authenticator is being replaced; to use it you need
to follow the directions in net80211/Makefile.
When operating as an AP, you can use fixed/shared key ciphers and/or
802.1x authentication. The authentication mode is specified using
iwpriv:
iwpriv ath0 authmode 1 # open authentication
iwpriv ath0 authmode 2 # shared key authentication
iwpriv ath0 authmode 3 # 802.1x authentication
To use the 802.1x authenticator you must install and configure the
hostapd program from the same place you got wpa_supplicant from.
Consult the hostapd documentation for further information.
Live Monitoring and Writing Raw 802.11 Packets
----------------------------------------------
The driver can be used in a live "monitor" mode, by creating a monitor
VAP and sending packets to it. All packets sent to a monitor mode VAP
will bypass any state machine.
To create a monitor VAP, use:
wlanconfig ath1 create wlandev wifi0 wlanmode monitor
ifconfig ath1 up
Finally, you can choose to receive packets on ath1 in several different
packet formats:
echo '801' > /proc/sys/net/ath1/dev_type # only 802.11 headers
echo '802' > /proc/sys/net/ath1/dev_type # prism2 headers
echo '803' > /proc/sys/net/ath1/dev_type # radiotap headers
echo '804' > /proc/sys/net/ath1/dev_type # atheros descriptors
Known Problems
--------------
[All these problems are to be fixed in future revisions.]
1. Ad-hoc mode is broken; symptoms are intermittent operation.
Other issues might be mentioned in our ticket tracker:
http://madwifi.org/report/1
Getting Support
---------------
User support is provided via the madwifi-users mailing list, which can
be reached at:
madwifi-users@lists.sourceforge.net
Contact this mailing list if you need help in getting your installation
up and running. We suggest that you subscribe to the list before
sending your request (see below).
We also offer an IRC channel that might be a better help in urgent
cases. Learn more about the different ways to get support by visiting:
http://madwifi.org/wiki/Support
When sending a support request or problem report be sure to include the
version of the driver and the part identification the driver prints to
the console when the module is loaded. For example:
ath_hal: 0.8.2.0
wlan: 0.7.0.0
ath_pci: 0.8.2.0
PCI: Found IRQ 11 for device 00:13.0
ath0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ath0: 802.11 address: 00:05:5d:6f:99:5f
ath0: Atheros 5211: mem=0xfebf0000, irq=11
This says the HAL module is version 0.8.2, the wlan module is version
0.7, the driver is version 0.8.2 and the hardware uses an Atheros 5211
chip (which supports 11a and 11b modes).
We will try to respond in a timely manner but understand this software
is provided as-is, without any promise of support.

the HAL lock.

Minstrel
Introduction
==================================================================
This code is called minstrel, because we have taken a wandering minstrel
approach. Wander around the different rates, singing wherever you
can. And then, look at the performance, and make a choice. Note that the
wandering minstrel will always wander in directions where he/she feels he/she
will get paid the best for his/her work.
The Minstrel autorate selection algorithm is an EWMA based algorithm and is
derived from
1)An initial rate module we released in 2005,
http://sourceforge.net/mailarchive/forum.php?forum_id=33966&max_rows=25&style=flat&viewmonth=200501&viewday=5
2)the "sample" module in the madwifi-ng source tree.
The code released in 2005 had some algorithmic and implementation
flaws (one of which was that it was based on the old madwifi codebase)
and was shown to be unstable. Performance of the sample module is poor
(http://www.madwifi.org/ticket/989), and we have observed similar
issues.
We noted:
1)The rate chosen by sample did not alter to match changes in the radio
environment.
2)Higher throughput (between two nodes) could often be achieved by fixing the
bitrate of both nodes to some value.
3)After a long period of operation, "sample" appeared to be stuck in a low
data rate, and would not move to a higher data rate.
We examined the code in sample, and decided the best approach was a
rewrite based on sample and the module we released in January 2005.
Theory of operation
==================================================================
We defined the measure of successfulness (of packet transmission) as
mega-bits-transmitted
Prob_success_transmission * ----------------------
elapsed time
This measure of successfulness will therefore adjust the transmission speed to
get the maximum number of data bits through the radio interface. Further, it
means that the 1mb/sec rate (which has a very high probability of successful
transmission) will not be used in preference to the 11mb/sec rate.
We decided that the module should record the successfulness of all packets
that are transmitted. From this data, the module has sufficient information to
decide which packets are more successful than others. However, a variability
element was required. We had to force the module to examine bit rates other
than optimal. Consequently, some percent of the packets have to be sent at
rates regarded as non optimal.
10 times a second (this frequency is alterable by changing the driver code)
a timer fires, which evaluates the statistics table. EWMA calculations
(described below) are used to process the success history of each rate. On
completion of the calculation, a decision is made as to the rate which has the
best throughput, second best throughput, and highest probability of success.
This data is used for populating the retry chain during the next 100 ms.
As stated above, the minstrel algorithm collects statistics from all packet
attempts. Minstrel spends a particular percentage of frames, doing "look
around" i.e. randomly trying other rates, to gather statistics. The
percentage of "look around" frames, is set at boot time via the module
parameter "ath_lookaround_rate" and defaults to 10%. The distribution of
lookaround frames is also randomised somewhat to avoid any potential
"strobing" of lookaround between similar nodes.
TCP theory tells us that each packet sent must be delivered in under 26ms. Any
longer duration, and the TCP network layers will start to back off. A delay of
26ms implies that there is congestion in the network, and that fewer packets
should be injected to the device. Our conclusion was to adjust the retry chain
of each packet so the retry chain was guaranteed to be finished in under 26ms.
Retry Chain
==================================================================
The HAL provides a multirate retry chain - which consists of four
segments. Each segment is an advisement to the HAL to try to send the current
packet at some rate, with a fixed number of retry attempts. Once the packet is
successfully transmitted, the remainder of the retry chain is
ignored. Selection of the number of retry attempts was based on the desire to
get the packet out in under 26ms, or fail. We provided a module parameter,
ath_segment_size, which has units of microseconds, and specifies the maximum
duration one segment in the retry chain can last. This module parameter has a
default of 6000. Our view is that a segment size of between 4000 and 6000
seems to fit most situations.
There is some room for movement here - if the traffic is UDP then the limit of
26ms for the retry chain length is "meaningless". However, one may argue that
if the packet was not transmitted after some time period, it should
fail. Further, one does expect UDP packets to fail in transmission. We leave
it as an area for future improvement.
The (re)try segment chain is calculated in two possible manners. If this
packet is a normal tranmission packet (90% of packets are this) then the retry
count is best throughput, next best throughput, best probability, lowest
baserate. If it is a sample packet (10% of packets are this), then the retry
chain is random lookaround, best throughput, best probability, lowest base
rate. In tabular format:
Try | Lookaround rate | Normal rate
------------------------------------------------
1 | Random lookaround | Best throughput
2 | Best throughput | Next best throughput
3 | Best probability | Best probability
4 | Lowest Baserate | Lowest Baserate
The retry count is adjusted so that the transmission time for that section of
the retry chain is less than 26 ms.
After some discussion, we have adjusted the code so that the lowest rate is
never used for the lookaround packet. Our view is that since this rate is used
for management packets, this rate must be working. - Alternatively, the link
is set up with management packets, data packets are acknowledged with
management packets. Should the lowest rate stop working, the link is going to
die reasonably soon.
Analysis of information in the /proc/net/madwifi/athX/rate_info file
showed that the system was sampling too hard at some rates. For those
rates that never work (54mb, 500m range) there is no point in sending
10 sample packets (<6ms time). Consequently, for the very very low
probability rates, we sample at most twice.
The retry chain above does "work", but performance is suboptimal. The
key problem being that when the link is good, too much time is spent
sampling the slower rates. Thus, for two nodes adjacent to each other,
the throughput between them was several megabits/sec below using a
fixed rate. The view was that minstrel should not sample at the slower
rates if the link is doing well. However, if the link deteriorates,
minstrel should immediately sample at the lower rates.
Some time later, we realised that the only way to code this reliably
was to use the retry chain as the method of determining if the slower
rates are sampled. The retry chain was modified as:
Try | Lookaround rate | Normal rate
| random < best | random > best |
--------------------------------------------------------------
1 | Best throughput | Random rate | Best throughput
2 | Random rate | Best throughput | Next best throughput
3 | Best probability | Best probability | Best probability
4 | Lowest Baserate | Lowest baserate | Lowest baserate
With this retry chain, if the randomly selected rate is slower than the
current best throughput, the randomly selected rate is placed second in the
chain. If the link is not good, then there will be data collected at the
randomly selected rate. Thus, if the best throughput rate is currently 54mbs,
the only time slower rates are sampled is when a packet fails in
transmission. Consequently, if the link is ideal, all packets will be sent at
the full rate of 54mbs. Which is good.
EWMA
==================================================================
The EWMA calculation is carried out 10 times a second, and is run for each
rate. This calculation has a smoothing effect, so that new results have
a reasonable (but not large) influence on the selected rate. However, with
time, a series of new results in some particular direction will predominate.
Given this smoothing, we can use words like inertia to describe the EWMA.
By "new results", we mean the results collected in the just completed 100ms
interval. Old results are the EWMA scaling values from before the just
completed 100ms interval.
EWMA scaling is set by the module parameter ath_ewma_level, and defaults to
75%. A value of 0% means use only the new results, ignore the old results.
A value of 99% means use the old results, with a tiny influence from the new
results.
The calculation (performed for each rate, at each timer interrupt) of the
probability of success is:
Psucces_this_time_interval * (100 - ath_ewma_level) + (Pold * ath_ewma_level)
Pnew = ------------------------------------------------------------------------------
100
number_packets_sent_successfully_this_rate_time_interval
Psuccess_this_time_interval=--------------------------------------------------------
number_packets_sent_this_rate_time_interval
If no packets have been sent for a particular rate in a time interval, no
calculation is carried out. The Psuccess value for this rate is not changed.
If the new time interval is the first time interval (the module has just been
inserted), then Pnew is calculated from above with Pold set to 0.
The appropriate update interval was selected on the basis of choosing a compromise
between
*collecting enough success/failure information to be meaningful
*minimising the amount of cpu time spent do the updates
*providing a means to recover quickly enough from a bad rate selection.
The first two points are self explanatory. When there is a sudden change in the radio
environment, an update interval of 100ms will mean that the rates marked as optimal are
very quickly marked as poor. Consequently, the sudden change in radio environment will
mean that minstrel will very quickly switch to a better rate.
A sudden change in the transmission probabilities will happen when the
node has not transmitted any data for a while, and during that time
the environment has changed. On starting to transmit, the probability
of success at each rate will be quite different. The driver must adapt
as quickly as possible, so as to not upset the higher TCP network
layers.
Module Parameters
====================================================
The module has three parameters:
name default value purpose
ath_ewma_level 75% rate of response to new data. A value of 100 is VERY responsive.
ath_lookaround_rate 10% percent of packets sent at non optimal speed.
ath_segment_size 6000 maximum duration of a retry segment (microseconds)
Test Network
====================================================
We used three computers in our test network. The first two, equipped with
atheros cards running in adhoc mode. We used a program that sends a fixed
number of TCP packets between computers, and reports on the data rate. The
application reports on the data rate - at an application layer level, which is
considerably lower than the level used in transmitting the packets.
The third computer had an atheros card also, but was running network monitor
mode with ethereal. The monitor computer was used to see what data rates were
used on the air. This computer was a form of "logging of the connection"
without introducing any additional load on the first two computers.
It was from monitoring the results on the third computer that we started to
get some confidence in the correctness of the code. We observed TCP
backoffs (described above) on this box. There was much celebration when the
throughput increased simply because the retry chain was finished in under 26
ms.
Our view was that throughput between the two computers should be as
close as possible (or better than) what can be achieved by setting
both ends to fixed rates. Thus, if setting the both ends to fixed
rates significantly increases the throughput, a reasonable conclusion
is that a fault exists in the adaptive rate rate.
We recorded throughputs (with minstrel) that are within 10% of what is
achieved with the experimentally determined optimum fixed rate.
Notes on Timing
====================================================
As noted above, Minstrel calculates the throughput for each rate. This
calculation (using a packet of size 1200 bytes) determines the
transmission time on the radio medium. In these calculations, we assume a
contention window min and max value of 4 and 10 microseconds respectively.
Further, calculation of the transmission time is required so that we can
guarantee a packet is transmitted (or dropped) in a minimum time period.
The transmission time is used in determining how many times a packet
is transmitted in each segment of the retry chain.
Indeed, the card will supply the cwmin/cwmax values directly
iwpriv if_name get_cwmin <0|1|2|3> <0|1>
We have not made direct calls to determine cwmin/cwmax - this is an area
for future work. Indeed, the cwmin/cwmax determination code could check to
see if the user has altered these values with the appropriate iwpriv.
The contention window size does vary with traffic class. For example,
video and voice have a contention window min of 3 and 2 microseconds
respectively. Currently, minstrel does not check traffic class.
Calculating the throughputs based on traffic class and bit rate and
variable packet size will significantly complicate the code and require
many more sample packets. More sample packets will lower the throughput
achieved. Thus, our view is that for this release, we should take a simple
(but reasonable) approach that works stably and gives good throughputs.
Values of cwin/cwmax of 4 and 10 microseconds are from
IEEE Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer
(PHY) specifications, Amendment : Medium Access Control (MAC) Enhancements for
Quality of Service (QoS) P802.11e/D12.0, November 2004.
Internal variable reporting
====================================================
The minstrel algorithm reports to the proc file system its internal
statistics, which can be viewed as text. A sample output is below:
cat /proc/net/madwifi/ath0/rate_info
rate data for node:: 00:02:6f:43:8c:7a
rate throughput ewma prob this prob this succ/attempt success attempts
1 0.0 0.0 0.0 0( 0) 0 0
2 1.6 92.4 100.0 0( 0) 11 11
5.5 3.9 89.9 100.0 0( 0) 11 11
11 6.5 86.6 100.0 0( 0) 10 11
6 4.8 92.4 100.0 0( 0) 11 11
9 6.9 92.4 100.0 0( 0) 11 11
12 9.0 92.4 100.0 0( 0) 11 11
18 12.1 89.9 100.0 0( 0) 11 11
24 15.5 92.4 100.0 0( 0) 11 11
36 20.6 92.4 100.0 0( 0) 11 11
t 48 23.6 89.9 100.0 0( 0) 12 12
T P 54 27.1 96.2 96.2 0( 0) 996 1029
Total packet count:: ideal 2344 lookaround 261
There is a separate table for each node in the neighbor table, which will
appear similar to above.
The possible datarates for this node are listed in the column at the left. The
calculated throughput and "ewma prob" are listed next, from which the rates
used in retry chain are selected. The rates with the maximum throughput,
second maximum throughput and maximum probability are indicated by the letters
T, t, and P respectively.
The statistics gathered in the last 100ms time period are displayed in the
"this prob" and "this succ/attempt" columns.
Finally, the number of packets transmitted at each rate, since module loading
are listed in the last two columns. When interpreting the last four columns,
note that we use the words "succ" or "success" to mean packets successfully
sent from this node to the remote node. The driver determines success by
analysing reports from the hal. The word "attempt" or "attempts" means the
count of packets that we transmitted. Thus, the number in the success column
will always be lower than the number in the attempts column.
When the two nodes are brought closer together, the statistics start changing,
and you see more successful attempts at the higher rates. The ewma prob at the
higher rates increases and then most packets are conveyed at the higher rates.
When the rate is not on auto, but fixed, this table is still
available, and will report the throughput etc for the current bit
rate. Changing the rate from auto to fixed to auto will completely
reset this table, and the operation of the minstrel module.

%description
This software contains a Linux kernel driver for Atheros-based
Wireless LAN devices. The driver supports station, AP, ad-hoc, and
monitor modes of operation. The Atheros driver depends on a
device-independent implementation of the 802.11 protocols that
originated in the BSD community (NetBSD in particular).
The driver functions as a normal network device and uses the Wireless
Extensions API. As such normal Linux tools can and should be used
with it. Where the wireless extensions are lacking private ioctls
have been added.
There is only one driver included here; it supports PCI, miniPCI
and Cardbus devices - USB devices are currently not supported by
this driver! The driver can be built as a module or linked
directly into the kernel. Note however that the net80211 layer is
device-independent; there is no reason it cannot be used with any
802.11 device (in fact on BSD systems this is the case).
There are currently 3 "programming generations" of Atheros 802.11
wireless devices (some of these have multiple hardware implementations
but otherwise appear identical to users):
5210 supports 11a only
5211 supports both 11a and 11b
5212 supports 11a, 11b, and 11g
%package module
Summary: A linux device driver for Atheros chipsets (ar5210, ar5211, ar5212).
Group: System Environment/Kernel
Requires: kernel = %{mykversion}
Release: 6_%{mykrelver}
%description module
This software is broken into multiple modules. The Atheros-specific
device support is found in the ath_pci module; it should be loaded
when an Atheros wireless device is recognized. The ath_pci module
requires an additional device specific module, ath_hal, which is
described more below. In addition the driver requires the wlan
module which contains the 802.11 state machine, protocol support,
and other device-independent support needed by any 802.11 device.
This code is derived from work that first appeared in NetBSD and
then FreeBSD. The wlan module may also force the loading of
additional modules for crypto support (wlan_wep, wlan_tkip, wlan_ccmp,
etc.), for MAC-based ACL support (wlan_acl), and for 802.1x
authenticator support (wlan_auth, wlan_radius)). The latter modules
are only used when operating as an AP. The crypto modules are
loaded when keys of that type are created.

Atheros Hardware Access Layer (HAL)
===================================
* Copyright (c) 2002-2006 Sam Leffler.
* Copyright (c) 2002-2006 Atheros Communications, Inc.
* All rights reserved.
Read the file COPYRIGHT for the complete copyright.
This code manages much of the chip-specific operation of the Atheros
driver. The HAL is provided in a binary-only form in order to
comply with local regulatory agency rules. In the United States
the FCC requires that a radio transmitter only be operated at power
levels and on frequency channels for which it is approved. The FCC
requires that a software-defined radio cannot be configured by a
user to operate outside the approved power levels and frequency
channels. This makes it difficult to open-source code that enforces
limits on the power levels, frequency channels and other parameters
of the radio transmitter. See
http://ftp.fcc.gov/Bureaus/Engineering_Technology/Orders/2001/fcc01264.pdf
for the specific FCC regulation. Because the module is provided
in a binary-only form it is marked "Proprietary" on Linux; this
means when you load it you will see messages that your system is
now "tainted".
If you wish to use this driver on a platform for which an ath_hal
module is not already provided please contact the author. Note that
this is only necessary for new _architectures_; the HAL is not tied to
any specific version of your operating system.
Atheros Hardware
================
There are many generations of Atheros 802.11 wireless devices that
are typically referred to by their programming model:
5210 supports 11a only
5211 supports both 11a and 11b
5212 supports 11a, 11b, and 11g
These parts have been incorporated in a variety of retail products
including cardbus cards and mini-pci cards. In addition many laptop
vendors use Atheros mini-pci cards for their builtin wireless
support.
The Atheors PCI vendor id is 0x168c. The file ah_devid.h lists most
known PCI device id's but is not exhaustive. Some vendors program
their own vendor and/or device id's to aid in BIOS-locking mini-pci
cards in laptops.
Atheros SoC Hardware
====================
In addition to the cardbus/pci devices Atheros makes System on Chip
(SoC) parts that integrate a MIPS cpu core and one or more MAC and
radio parts. Binary support for these parts is necessarily built
for the embedded MIPS processor where the code is to be run.
Caveats
=======
The binary hal builds provided here include no floating point and
are operating system-independent. However due to toolchain
peculiarities the .o files may be wrongly rejected by development
tools. If that happens it may be possible to patch the file header
so that the native toolchain will accept the files. In particular
this has been observed for various Linux MIPS installations for the
SoC parts. If you have issues consult the associated .inc file in
the public directory; it explains exactly how the binary file was
created (e.g. toolchain and compilation options).
