摘要 该文在对原有的IEEE 802.11 DCF研究的基础上,提出了一种基于最小竞争窗口自适应调整的退避算法(Minimum Contention Window Self-adaptive Adjusting,MCWSA)。该算法的思想是每个站点根据网络中当前的时隙利用率和理论上最优时隙利用率进行比较,周期性动态调整自身的最小竞争窗口,以适应不同的网络拥塞状况。仿真表明,该算法提高了IEEE 802.11局域网在拥塞情况下的性能,在饱和吞吐量和时延上都有不同程度的改善。 A backoff algorithm based on Minimum Contention Window Self-adaptive Adjusting （MCWSA） is proposed in this paper. The idea of this algorithm is that every node in the network adjusts self minimum contention window periodically, according to the comparing result of the present slot utilization and the optimal value, to adopt the congestion status. Simulation result proves that MCWSA can enhance the IEEE 802.11 performance in saturation throughout and delay.
