High-throughput routing protocol in wireless mesh network

无线网状网(Wireless Mesh Network,WMN)是一种多跳、分布式的无线网络,可以提供多种宽带多媒体业务。目前,无线网状网的路由技术的研究还处于起步阶段。首先介绍当前几种著名的无线网状网路由协议,并分析了这些协议的不足,在此基础上提出一种新的路由算法,该算法综合考虑了链路质量、节点负载均衡、信道干扰三个主要因素,能够显著地提高网络性能。分析与仿真结果表明,该算法能显著地提高网络吞吐量和降低传输延时,并且具有良好的抗干扰性。

Wireless mesh network is a kind of multi-hop and distributed wireless network which can provide many sorts of wide-band multimedia services.At the present,the research of wireless network in routing technology is still at the starting stage. This paper firstly introduces several famous routing protocols in wireless mesh network and analyses the deficiency of those routing protocols,based on which,this paper then puts forward a new routing algorithm which can remarkably improve the performance of the network because of its comprehensive consideration on three factors： link quality,the balancing of load on each node and channel interference.The analysis and simulation results indicate that the new routing algorithm can evidently improve network throughputs and reduce transmission delay and it has nice interference immunity.
