摘要
针对移动Ad Hoc网络中节点链路断裂、路由需要不断进行维护的问题,在按需距离矢量路由(AODV)协议基础上结合链路质量指示器,添加对节点电池电量的监测功能,根据节点剩余能量进行路由预测及预修复,在对链路状况提前做出判断的基础上及时进行路由切换,避免路由频繁中断。仿真表明,改进协议提高了数据包投递率,降低了端到端延迟时间,使网络更加稳定高效。
In order to solve the problems of the breakdown of node link and the constantly maintenance of route in the mobile Ad Hoc network, based on the existing Ad Hoc on-demand distance vector routing （AODV） pro- tocol, combined with the link quality indicator, a monitoring function of the node battery power is added. It can not only perform route prediction and pre-restoration according to the residual energy of nodes, but also prompt- ly switch routing to avoid frequent interruption of routing on the basis of checking the link status. The simula- tion of the improved protocol in NS2 proves that this protocol can improve the packet delivery rate, reduce the end-to-end delay and make the network more stable and efficient.
