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.
In wireless Mesh networks, it is a common method to optimize the network performance by reasonably designing routing metrics.This paper analyzes and discusses the existing typical routing metrics, and gives a comprehensive description of the design of the wireless Mesh network routing metrics As an important factor.According to the characteristics of multi-channel wireless Mesh network, this paper proposes a multi-channel wireless Mesh network routing metric CLIDH, and on this basis proposes a cross-layer multi-channel routing protocol CMAODV.The simulation results show that, with the existing routing metric phase In comparison, CLIDH can make full use of network resources, so that network performance can be significantly improved.
