now configure the HAL, bus, default rate control algorithm as well as the debug mode from within make menuconfig. The goal is to be able to support hardware profiles with different HALs without messing around with the Makefile directly.

This code is takes 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.

config MADWIFI_RCA_ONOE
|
|
bool "Use the Onoe rate control algorithm"
|
|
help
|
|
Onoe is a credit based RCA where the value of the credit is determined
|
|
by the frequency of successful, erroneous and retransmissions
|
|
accumulated during a fixed invocation period of 1000 ms. If less than
|
|
10% of the packets need to be retransmitted at a particular rate, Onoe
|
|
keeps increasing its credit point till the threshold value of 10 is
|
|
reached. At this point, the current transmission rate is increased to
|
|
the next available higher rate and the process repeated with credit
|
|
score of zero. Similar logic holds for deducting the credit score and
|
|
moving to a lower bit-rate for failed packet
|
|
transmission/retransmission attempts. However, once a bit-rate has
|
|
been marked as failure in the previous attempt, Onoe will not attempt
|
|
to select that bit-rate until 10 seconds have elapsed since the last
|
|
attempt. Due to the manner in which it operates, Onoe is conservative
|
|
in rate selection and is less sensitive to individual packet failure.

config MADWIFI_RCA_AMRR
|
|
bool "Use the AMRR rate control algorithm"
|
|
help
|
|
AMRR uses Binary Exponential Backoff (BEB) technique to adapt the
|
|
length (threshold) of the sampling period used to change the values of
|
|
bit-rate and transmission count parameters. It uses probe packets and
|
|
depending on their transmission status adaptively changes the threshold
|
|
value. The adaptation mechanism ensures fewer failed
|
|
transmission/retransmission and higher throughput by not switching to a
|
|
higher rate as specified by the backoff mechanism. In addition to this,
|
|
the AMRR employs heuristics to capture the short-term variations of the
|
|
channel by judiciously setting the rate and transmission count
|
|
parameters.
|
|
|
|
config MADWIFI_RCA_SAMPLERATE
|
|
bool "Use the SampleRate rate control algorithm"
|
|
help
|
|
SampleRate decides on the transmission bit-rate based on the past
|
|
history of performance; it keeps a record of the number of successive
|
|
failures, the number of successful transmits and the total transmission
|
|
time along with the destination for that bit-rate. Stale samples are
|
|
removed based on a EWMA windowing mechanism. If in the sampling
|
|
process, no successful acknowledgment is received or the number of
|
|
packets sent is multiple of 10 on a specific link, it transmits the
|
|
packet with the highest rate which has not failed 4 successive times.
|
|
Other than that it transmits packets at the rate which has the lowest
|
|
average transmission time.
