摘要：In the IEEE 802.11MAC layer protocol, the basic access method is the Distributed Coordination Function which is based on the CSMA/CA. In this paper, we investigate the performance of IEEE 802.11 DCF in the non-saturation condition. We assume that there is a fixed number n of competing stations and packet arrival process to a station is a poisson process. We model IEEE 802.11 DCF in non-saturation mode by 3-dimensional Markov chain and derive the stationary distribution of the Markov chain by applying matrix analytic method. We obtain the probability generating function of packet service time and access delay, and throughput.
