【摘要】 传统的AODV路由协议无法适应Adhoc网络拓扑的高度动态变化。对AODV路由算法进行链路可用性预测扩展,节点通过接收分组的能量值和链路连续可用时间选择最可靠的路径进行路由,并在链路真正失效之前启动预先修复过程。仿真结果表明,改进后的AODV协议提高了分组的投递率,降低了分组端到端平均传输延时,路由协议的可靠性得到改进。更多还原

【Abstract】 The AODV routing protocol could not adapt to high dynamic topology change well. According to extend the AODV routing algorithm by the link availability prediction, the nodes selected the most stable path to route based on the power of received packets and the link continuous availability time, and started the route maintenance in advance before the link broken. The simulation results demonstrate that the improved AODV routing protocol increased the packet deliv- ery ratio and decreases the average end-to-end delay, and the reliability of the routing protocol is strengthened.更多还原
