摘要: 针对AODV协议运行时路由相对稳定的特点,提出一种AODV协议运行时优化方法。该方法通过Hello消息和邻居节点进行信息交换,根据路由跳数、节点电池电量和射频信号强度3个链路状态值动态选择最优路由,实现AODV协议的运行时优化。仿真实验结果证明,改进的路由协议能够有效增加数据包投递率,减少平均端到端延时。

Abstract: According to the characteristic of Ad hoc On-demand Distance Vector(AODV) protocol which is relatively stable on the running time, a running time optimization method of AODV is proposed. The method exchanges the information between neighbor nodes and selects the optimal route to implement the routing optimization by the three link state values of route hop counts, battery power of nodes and RF signal strength. Simulation results prove that the improved routing protocol can increase packet delivery ratio and reduce average end-to-end delay.
