中文摘要：

由于无线网状网具有多网卡多信道、节点移动性低等特性，使用传统的基于最短路径的移动AdHoc网络路由协议并不能获得良好的性能，为此提出了一种新的无线网状网路由协议——MEIL算法．通过引入链路干扰度、节点负载度等概念，综合考虑了无线信道的丢包率、链路干扰以及节点的负载等多种重要因素，来确定路由判据，选择链路质量好、干扰小、负载轻的路径来传输数据，有效地提高了网络吞吐量．仿真结果表明，MEIL算法比AODV路由协议和DSDV＋ETX算法更适用于无线网状网，在各种业务环境下其吞吐量、时延、到达报文量等性能均具有更好的效果．

英文摘要：

Because of the unique characteristics over wireless mesh networks, such as muhi-radio multi-channel and static nodes, traditiohal Ad hoc network routing protocols based on the condition of ＂shortest path＂cannot work very well. This paper presents a novel routing protocol named MEIL for wireless mesh networks. It designs routing metrics according to the wireless link loss, interference between channels and the load of wireless mesh nodes. MEIL chooses the route with lower loss, smaller interference and lighter load, so it can improve the throughput of the network efficiently. The simulation results show that MEIL performs much better than the AODV routing protocol and the DSDV ＋ ETX algorithm under the circumstances of various services, and it is suitable for wireless mesh networks.
