无线Mesh网络由于拓扑结构、Mac协议、路由协议以及信道分配策略的复杂多变,其系统平均时延分析一直没有得到很好的解决。提出了一种基于排队论的时延分析模型,分析了在任意拓扑结构和路由协议下,处于基础工作模式的无线Mesh网络平均时延,并同时考虑了多收发器、多信道的影响。计算机仿真结果表明该模型能够比较准确的估计出网络性能,可以为无线Mesh网络部署以及优化提供理论依据。
Due to the complexity of topologies, Mac protocols, routing protocols and channel allocation strategies, wireless Mesh Networks has not been able to solve the average system latency analysis. A time delay analysis model based on queuing theory is proposed. The average time delay of wireless Mesh network in basic working mode under any topology and routing protocol is analyzed, and the effects of multiple transceivers and multiple channels are also considered. Computer simulation results show that this model can estimate the network performance more accurately and provide a theoretical basis for the deployment and optimization of wireless Mesh networks.
