摘要： 通过搭建基于IEEE 802.11b/g协议的无线Mesh网络实验床，测试无线链路的吞吐率和延迟。实验结果表明，无线链路延迟随跳数增加而增加。利用多发射多信道的网络架构，在无线链路各跳间实现并行传输数据，保证了端到端的吞吐率，使网络性能不会因为无线跳数的增加而明显衰减。

Abstract: Through the experiments conducted on the practical Wireless Mesh Network(WMN) test bed based on IEEE 802.11b/g, this paper comes to the conclusion that the delay of wireless link increases with hops. The performance of WMN does not decrease significantly because of the multi-radio multi-channel architecture used by the WMN test bed. With this architecture, all hops of wireless link can work parallel, which guarantees the end-to-end throughput.

Key words: Wireless Mesh Network(WMN), multi-radio multi-channel, IEEE 802.11b/g protocol, performance
