摘　　要：提出了一种应用于无线Mesh网络的面向吞吐量效率的机会主义路由算法.研究了机会主义路由算法中转发节点数量与质量的制约关系,并通过分析多转发节点的转发特性,提出一种新的路径度量及相应的转发节点选择与排序算法.该方法引入了传输时间因素,在转发节点数量与链路稳定度之间取得了较好的平衡.仿真结果表明,本文算法能有效提高网络性能.A throughput efficiency oriented opportunistic routing algorithm for wireless Mesh networks is proposed. The relationship between the qualities and quantities of forwarding nodes is researched. The forwarding characteristics of multi-forwarders are analysed. Consequently,a new routing metric and a corresponding forwarder selection algorithm is presented successively. With this method, we will achieve a better balance between the number of forwarders and link stability for introducing the factor of transmission time. Simulations show that the proposed algorithm can achieve higher end-to-end throughput with fewer number of forwarding nodes and transmissions.
