一种基于链路状态组合度量的无线网状网路由协议

在分析Ad hoc网络中的经典路由协议AODV的基础上,结合无线网状网的特点,提出了基于链路加权的无线网状网路由协议MODVWLS.协议通过节点的可用带宽、缓冲队列和吞吐性能等计算每一跳的代价(即权重),选择从信源到信宿累计权重最小的路径作为路由.对链路权重计算、报文格式、路由发现和维护过程进行了详细阐述,并利用NS2对MODVWLS协议进行了仿真实现.结果表明,MODVWLS协议能合理利用空闲节点和链路资源,较好地均衡网络负载,在数据包转发率、端到端延迟和标准化路由负载等性能上均优于AODV协议.

Routing Protocol for Wireless Mesh Network Based on Combinative Metric of Link State

Although wireless mesh network is one of the most hotspots in wireless network field,the routing protocol standardization is still on the way.Anovel routing protocol for wireless mesh network,MODVWLS,was proposed by using weighted path as routing metric.Each node periodically calculates its weight which is composed of its bandwidth,cache queues and the throughput.MODVWLS chooses the path,which has the smallest accumulative weight from source to destination,as routing path.Weight calculation,message formats,...
