This paper describes a scheme, AEDCF-CW/PF, that allows stations implementing IEEE 802.11e to have varying maximum contention window sizes and persistence factors. The values of these parameters are adjusted using knowledge of the station’s collision probability. Our research indicates that stations implementing this scheme experience much lower frame delays and frame dropping probabilities under heavy loads. In addition, this scheme has the benefit of not requiring many modifications within the station.
