摘　　要：多路径路由可以有效地增加网络的吞吐量以及平衡网络负载。为了解决无线多跳网中多路径的负载均衡问题,提出了一种基于次短路径的多径路由策略——短多路径的无线路由协议。该协议是在M-WRP协议基础上,提供了节点相互分离的最短路径和次短路径的路由选择,通过将分组分配在两条路径上传输,可以缓解网络中拥塞的产生。仿真结果显示其与M-WRP协议相比,在业务量较重的情况下,提高了分组的递交率,降低了平均端到端时延,获得了对网络传输性能的改善。The multi-path routing can increase the throughput and balance load of network.In order to balance the load in wireless multi-hop networks,a novel multi-path routing strategy with the sub-shortest route is proposed,referred as Sub-shortest Multiple-path Wireless Routing Protocol(SM-WRP)protocol.The SM-WRP protocol provides multiple node-disjoint routes,which may include a shortest route and a sub-shortest one.And distributes the traffic in these paths to alleviate the congestion generation.The performance comparison with Multiple path Wireless Routing Protocol(M-WRP)by simulation shows that the proposed SM-WRP can achieve an improvement over M-WRP in terms of packet delivery ratio and average end-to-end delay under the heavy load situation.
