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. + +endchoice
