摘要
为了弥补802.11DCF机制的缺陷,通过调节网络节点竞争窗口CW的大小和增长速度来改进该机制的指数退避算法。改进的算法可以使得处于信道冲突严重时的节点获得较多的信道接入机会。
In this paper, in order to compensate for the defects of 802. llDCF mechanism, the size and growth rate of competition window are dynamically adjusts for the improvement of the Binary Exponential Back-off algorithm. The improved algorithm makes the nodes with more opportunities to access channel in serious channel conflict.
