摘　　要：AODV协议以源到目的的最短路径或最短跳数作为路由度量参数。LA_AODV协议综合考虑无线移动自组织网络的路由层和物理层,提出了一种新的路由度量参数。首先介绍了LA_AODV协议,然后讲述在NS2中实现LA_AODV的方法,并详细分析仿真中的关键问题。仿真结果表明LA_AODV协议在保持AODV协议特点的基础上,具有吞吐量高、路由开销低、延时小的特点。Ad Hoc On - demand Distance Vector （AODV） routing protocol selects the shortest-path or minimum hop count from source to destination as route selection metric. A new route selection metric was proposed in Link-quality Aware AODV （ LA_AODV）. It took route layer and physical layer into account. LA_AODV was introduced, and then the method of simulating LA_AODV in NS2 was expatiated. Some key problems were discussed. The simulation results show that LA_AODV protocol introduces much lower routing overhead while still providing better performance than AODV protocol in terms of throughput, cost and delay.
