摘　　要：无线Mesh网络是由客户节点、Mesh路由器节点和网关节点组成的,基于多跳路由、对等网络技术的高速率、高容量的新型网络,如何设计适合该环境的路由协议和算法,是无线Mesh网络领域的一个重要研究内容。本文提出了一种基于RARP路由协议(Radio Aware Routing Protocol,射频感知路由协议)的改进路由判据——加权的包期望传输时间路由判据(W-ETT)。W-ETT使用了加权平均的思想,在有效降低数据传输中丢包率的同时,显著提高了网络的吞吐量。仿真结果表明,新路由判据能有效地改善网络性能,对无线Mesh网络路由算法的研究具有一定的指导意义。Wireless mesh networks consist of mesh clients, mesh routers and gateways; based on the new network of multi-hop routing, peer-to-peer technology, high-speed, high capacity. How to design a wise routing protocol and related algorithms for wireless mess networks is .an important research topic in its domain. The paper proposes a modified version of the routing metric of the popular RARP protocol, named W-ETT, which is Weighted Expected Transmission Time routing metric. Utilizing the weighted mean algorithms, W-ETT cuts down the Packet Lost Ratio, and at the same time improves the network throughput greatly. It is demonstrated in the simulation that the new routing metric can improve the wireless Mesh network performance, and has some instructional significance for studying the wireless Mesh network routing algorithm.
