摘要
现多数路由协议仅考虑单个路由度量,为此,提出基于多路由度量的无线Mesh网络路由协议MMR(multi-routing metric routing),提高WMNs的性能。通过融合数据包丢失率、干扰以及网关的负荷信息,选择最佳的路径传输数据。仿真结果表明,该MMR协议的性能优于基于期望传输次数ETX(expected transmission)、最近网关NG(nearest gateway)、网关负荷LG(load at gateways)和干扰率IR(interference ratio)的单个路由度量的路由协议,与基于LG、ETX、NG、IR的路由协议相比,MMR协议的吞吐量分别提高了近33%、26%、13%、10%,端到端传输时延下降了近35%、28%、17%、11%。
Most of current routing protocols only take one metric into account at most.Therefore,multi-routing metric routing（MMR）protocol was proposed,which improved the performance of WMNs.A routing metric was used,which was a combination of packet losses,intraflow and interflow interferences,and load at gateways,to select best paths to reach selected gateways.Simulation results show that the proposed method improves the network performance and outperforms existing routing schemes,which are based on expected transmission count（ETX）,nearest gateway（NG）,load at gateways（LG）,and interference ratio（IR）.More specifically,the proposed method yields 33%,26%,13%,and 10% more throughput compared with LG,ETX,NG,and IR,respectively.
