摘要
将链路预测机制引入AODV协议中,使节点利用接收分组的能量及时发现并删除缓存中的失效路由,并在此基础上利用跳数值进行了优化。仿真结果表明,改进后的AODV协议在高负载网络中明显降低了端到端分组平均时延,提高了网络中的报文投递率。
The link breakage prediction mechanism was introduced into the AODV protocol in this paper. The mobile node used the signal strength from the received packets to find and remove the invalid routing information in time. In addition,the improved protocol was optimized by using hop numbers. The simulation shows the improved AODV protocol could reduce the end-to-end delay effectively and increase the packet delivery ratio in high load network.
