| 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.

| Abstract: | 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 t... |
