基于AODV的自组网QoS路由协议

AODV-Based Routing Protocol with QoS Support

该文在AODV协议的基础上,设计了保证实时业务服务质量的路由协议Q-AODV。该协议针对无线环境的共享媒体特性,定义了节点的'共享频率集',以节点周围的剩余可预约带宽作为路由度量的主要参数,回避可能发生拥塞的链路,同时提高了网络的整体效率。仿真结果表明:该算法保证了实时业务的服务质量,在数据包的传输时延和网络的分组递交率方面优于原有协议。

To guarantee quality of service of real-time traffic, an algorithm based on AODV is presented. In this algorithm, node maintains traffic information of nodes in its neighborhood. Reservable bandwidth is used as the main consult in routing.Simulation shows that the QoS of real time traffic is guaranteed and the algorithm is superior to standard AODV routing algorithm in terms of delivery rate and mean end to end packet delay.
