基于NS2的改善802.11b无线网络传输效果异常仿真研究

The simulation research of improved 802.11b wireless network transmission performance anomaly based on NS2

针对多速率802.11b无线网络环境的数据传输效果异常现象,提出了一种在多速率无线网络环境下改善802.11b无线网络传输效果异常的新方法.该方法根据不同的数据传输速率同时调整数据帧及竞争窗口大小.仿真结果表明,该方法可以有效改善802.11b无线网络传输效果异常现象.

Aiming at the data transmission performance anomaly in multi-rate wireless local networks 802.11 b, a new method was proposed which adjusts the size of data frame and eontontion window accord- ing to the different data transmission rates to improve the performance anomaly in multi-rate wireless local networks, the simulation results showed that this method can effectively improve the performance anomaly in the 802.11 b wireless network.
