摘要: 在802.11WLAN中,竞争的站点数在网络性能的优化中是一个重要的参数。针对现有的概率测量法和中断测量法的实时性较高,但测量精度较差的问题,提出基于退避时间的竞争站点数测量法。该方法考虑站点的退避时间长短对测量结果的影响,对中断测量法进行改进,并给出实现算法。仿真实验结果表明,该方法是一种具有较好测量精度的测量方法。

Abstract: In 802.11 WLAN, the competition stations number is a very important parameter for optimizing the performance of the network. Aiming at the problem of that the current methods of probability measurement and interruption measurement have good performance in terms of real-time, but less in measurement accuracy. Aiming at the problem, this paper proposes a method based on back off time measurement. It improved interruption measurement considering the effect of back off time. Simulation experimental result shows that it is a efficient method.

Key words: Wireless Local Area Network(WLAN), competition stations number, back off time
