中文摘要: 首先简单介绍了无线局域网同频干扰产生的原因, 然后在NS2仿真平台上搭建高密度无线局域网环境. 通过仿真, 测量系统中总的数据吞吐量、端到端传输时延和平均吞吐量来探究高密度WLAN下同频干扰强弱程度随AP数增加的变化趋势. 仿真结果表明, 高密度WLAN下同频干扰强弱程度随AP数的增加遵循一定的变化规律, 这为实际规划接入节点时同频干扰强弱的控制提供了依据, 也为仿真研究高密度无线局域网提供了参考.

Abstract:In this paper, we first introduce the reasons of co-channel interference in WLAN, and then build a dense WLAN environment in NS2. We explore the strength of the co-channel interference, as the number of APs increase in a dense WLAN environment, by measuring its total throughput, end to end delay and the average throughput. The simulation results indicate that the strength of co-channel interference follow certain rules. It provides a basis for controlling the strength of co-channel interference when we plan the WLAN network. It also provides references for the simulation study of the dense WLAN.
