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。

关 键 词:无线移动自组织网络  链路感知  跨层设计  路由度量参数

Abstract: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.
Keywords:Mobile Ad Hoc NETworks (MANET)  link-quality aware  cross-layer design  route selection metric
