| 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.

Routing Prediction and Pre-Repair Based on AODV Protocol |

| Abstract: | 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) protocol,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 promptly switch routing to avoid frequent interruption of routing on the basis of checking the link status.The simulation 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. |
