摘　　要：在多跳Ad hoc网络中,CDMA方式便于向路由等上层提供物理链路信息,所以以链路质量作为参考量度,将其引入到路由建立、路由维护、本地管理等重要环节中,可以跨层设计新型AODV路由协议。分析和仿真表明,改进后的AODV协议提供了更合理的路由机制、节约了网络节点能量。In a CDMA-based multi-hop Ad-hoc system, it is convenient to provide physical links＇ information for upper layers. Being an important metric, link quality is used in the processes of route discovery, route maintenance and neighbor nodes management in the proposed cross-layer AODV protocol. Performance of energy efficiency was evaluated through simulation. It is shown that the approved protocol is more efficient in consumption of network resource and energy, and more flexible in obtaining an optimized path to destinations.
