摘　　要：AODV算法采用最少跳数的路径作为信源节点和信宿节点之间的通信路径,忽略了可能存在的低质量的信道。本文提出一种改进的基于链路质量的L-AODV路由协议,该协议在源节点广播RREQ请求分组并沿途收集链路质量信息,利用目的节点接收到的RREQ分组进行路径性能评估,并选择出链路质量最高的路径。实验结果表明基于链路质量的L-AODV协议可以明显提高分组投递率。AODV algorithm chooses the path between the source node and destination node according to the least hops of path,which ignores the possibility of the existence of low-quality links.The improved routing protocol L-AODV collects the link quality information during the broadcasting progress in network.According to the link quality information included in arrived RREQ packets,the destination nodes choose the path after evaluating the performance by computing path cost.Experimental results show that L-AODV routing protocol is improved in packet delivery rate.
