移动自组织网络路由协议的节能策略

Energy Saving Strategy in Ad Hoc Routing Protocal

本文针对移动自组织网绍环境,基于节点能量消耗速度提出了一个新的改进的AODV路由协议。该协议定义了一个有关节点剩余生命期与路由路径跳数的函数,并以该函数值作为路由选择参数进行最优路径的选择,从而使能量充足的节点获得更多参与通信的机会。该协议对网络中节点的能量消耗起到了很好的平衡作用,从而使网络生命期更长。基于NS-2网络模拟器,对该协议与AODV协议进行了模拟实验,实验结果表明。该协议的网络路由负载小,网络运行时间长。

A improved AODV based on the energy consumption speed of nodes in mobile Ad hoe networks is presented. A route select parameter computed by residual lifetime of nod es and hop count of route is used to be selected the best route, the nod es that have more energy have more probability of chosen. The mechanism can balance the energy consumption of nod e and prolong network＇ s life. Simulation result comparing with zone routing protocol in NS-2 shows AODV has lower routing overhead, and longer lifeeyele of network.
