摘　　要：为了进一步提高无线局域网EDCA机制信道利用率和吞吐率,提出一种EDCA参数的自适应调整改进算法并进行了仿真,该算法可使节点根据网络吞吐量变化情况,计算出冲突概率自动调节竞争窗口值,从而提高EDCA的性能。In order to further improve the channel utilization and throughput of WLAN EDCA mechanism,a kind of EDCA parameters adaptive adjustment algorithm is put forward and simulated.This algorithm can envoys points according to the change of the network throughput,calculate the probability of conflict and adjust competition window value automatically,thus the performance of the EDCA is improved.

关 键 词：EDCA自适应参数调整 冲突概率 竞争窗口
