一个基于能量消耗的域路由协议

A Zone Routing Protocol Based on Energy Consumption

针对移动Ad hoc网络环境,基于节点能量消耗速度提出了一个新的域路由协议EZRP。该协议中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ZRP协议进行了模拟实验,实验结果表明,该协议的节点死亡个数少,网络路由负载小,网络运行时间长。

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