摘要/Abstract

摘要：

在无线Mesh网络路由判据的研究中,最小跳数、ETX、ETT等路由判据没有考虑到无线网络中的干扰问题,据此选出的一般不是最佳路由。因此,基于它们的路由协议会对整个无线Mesh网络的延时、丢包率、吞吐量等性能产生较大影响。干扰感知型路由判据的提出对无线Mesh网络性能的提升起到了一定的作用。

Abstract:

In the study of routing metrics in wireless mesh networks,the metrics such as minimum hop counts,ETX,ETT etc.fail to take the interference problems of wireless networks into consideration,and the paths selected based on these metrics generally are not the optimal path.Therefore,those routing protocols based on them will affect the performance of the whole mesh network such as the network delay,packet loss rate,and throughput.The proposition of interference aware metrics improves the performance of wireless mesh network greatly.

Key words: wireless mesh network;interference aware;routing metrics
