摘　　要：无线Mesh网是一种新型的宽带无线接入网络,其中路由算法的设计是一个非常活跃的研究领域。WCETT路由判据仅适于单径路由协议,但是多路径路由能够提供负载平衡和较高的总带宽。为了提高网络性能,在综合考虑无线链路质量和信道间干扰的基础上,提出了一种新的多径路由判据CAM-WCETT。仿真结果表明,该方案能显著提高网络的吞吐量。Wireless mesh networks （WMNs） are new broadband access networks, in which the design of routing algorithms has become an active research field. WCETT routing metric is only applied to single path routing protocol, but the multipath routing can provide load balance and higher bandwidth. In order to improve the performance of networks, a new routing metric called CAM- WCETT is proposed in this paper, in which the quality of wireless channels and interference among links in the networks are considered. The simulation result shows that the scheme can improve the network throughput greatly.
