无线Mesh网络中基于信道流量干扰感知的路由协议

摘要

为了更精确地捕捉流量干扰、提高网络容量与实时性,针对多接口无线Mesh网络,提出了一种新的基于信道流量干扰的路由准则,该准则不仅能更精确地捕获两跳内的负载干扰,而且还集成了传输时延、丢包率和传输速率等因素.基于新准则,还提出了一种新的无线Mesh网络路由协议,该协议使用新准则选择路由.仿真结果表明,新协议相比AODV协议和AODV-WCETT协议,在平均吞吐量、端到端时延及数据包传送率等方面具有更好的性能.%In order to capture the traffic interference, improve the network capacity and the real-time property, this paper proposed a novel routing metric based on channel traffic interference awareness for multi-interface WMN.The new metric not only captured the load interference within two hops but also integrated transmission delay, packet loss ratio and transmission rate.Then, presented a novel routing protocol, which utilized the new metric to select the routing paths.The simulation results show that the new protocol has better performances in terms of the average throughput, end-to-end delay and packet deliver ratio, as compared with both AODV protocol and AODV-WCETT protocol.
