中文摘要：

在无线Mesh网络中，采用合理设计路由度量来优化网络性能是一种常用的方法．本文对已有的典型路由度量进行分析讨论，比较全面的给出了设计无线Mesh网路路由度量应该考虑的重要因素．基于多信道无线Mesh网络的特点，本文提出一个多信道无线Mesh网络路由度量CLIDH，并在此基础上提出一个跨层多信道路由协议CMAODV．仿真结果表明，和已有的路由度量相比较，CLIDH能够充分利用网络资源，使网络性能得到明显改善．

英文摘要：

In Wireless Mesh Networks, using rational design of rou6ng metrics used to optianize network performance is a commonly used method. This paper discusses the typical routing metrics, and gives all important factors which should be taken into account. Based on the characteristics of multi-channel Wireless Mesh Networks, this paper presents a multi-channel Wireless Mesh Networks routing metric CLIDH, and puts forward a multi-channel cross-layer routing protocol CMAODV. Simulation results show that, com- pared to the existing routing metric, CLIDH make full use of network resources, so that network performance is significantly improved.
