| 摘 要： | 为了提高无线网络信道资源的利用率,采用测量MAC层信道空闲率估算节点剩余带宽,跨层访问剩余带宽的方法,实现AODV协议的QoS扩展（CLQ-AODV）,并在NS2上仿真实现。仿真结果表明,CLQ-AODV协议的分组端到端平均时延和平均路由开销有所减少,分组投递率获得提高。

| Abstract: | In order to improve wireless networks channel resources and its utilization rate,the remaining available bandwidth of nodes and accessing residual bandwidth through cross layer are estimated by the channel idle rates based on the MAC layer,which achieves the QoS extension and simulation for AODV in NS2(CLQ-AODV).The simulation result show that the CLQ-AODV has been reduced the average delay of end to end packet and the average routing overhead with the increase of the packet delivery ratio. |
