Abstract

In this paper, we explore how to make RWBO+BEB support service differentiation. An analytical model is proposed to analyze how to choose the minimum contention windows according to the bandwidth ratios of stations. Based on the analysis, a novel service differentiated backoff algorithm for IEEE 802.11 DCF, named DS-RWBO, is proposed. The simulation results indicate that DS-RWBO can allocate the wireless bandwidth according to the bandwidth ratio of each station.
