摘　　要：HWMP路由协议采用标准空时开销判据进行路径选择时,仅考虑了链路中节点所消耗的信道资源总量,不能综合考虑链路的质量、负载及其受干扰的情况。针对该问题,论文提出了一种新的路径选择算法,该方法将MAC层中更多的信道质量参数提取到路由判据中来,能综合考虑复杂多变的无线信道多种因数,有助于提高无线网络吞吐量,降低端到端时延。经过仿真实验表明,新路由判别方法能够优化802.11s的路径选择,提高网络的整体性能。The router metric of hybrid wireless mesh protocol only considers the channel resource consumption,but pay no attention to other parameters of MAC layer for interference,link quality and congestion.So a new solution of router metric is proposed,which comprehensively considers various factors.The new metric will help increase the network throughput and reduce the end-to-end delay.Finaly,simulation results show that the new metric can optimize the path selection based on802.11 sand improve the overall performance of the network.
