由于EDSR路由协议在路由选择是采取向邻居节点全部转发路由信息的策略,在路由请求时,容易引起转发次数过多而导致网络瘫痪.本文提出借助LAR协议利用目的节点的位置信息设置路由的期望域,从而构建路由选择区域,提高发起路由请求时预知目的节点位置的几率,提出增强性LAR路由协议.当位置辅助路由协议发现路由失败时避免采用全网洪泛机制,采用基于距离的位置路由改进算法,设置距离更新门限来达到节点位置信息实时性与更新负载的平衡,通过路由选择权重值Qpath使路由选择达到最优.

Traditional EDSR routing protocol always transmits information to all neighboring nodes. When much routing requests occur, it is easy to induce that the network breaks down. This paper presents a location-aided routing by LAR routing procotol which makes up a zone with the destination node’s position information for selecting routing. The proposed routing algorithm can avoid flooding in the whole network. Besides, the distance update threshold is set up to reach the balance between real time ability and accuracy of location information of node, the routing selection optimization depends on the value of weight Qpath.
