摘　　要：传统的AD Hoc路由协议由于节点的能量不均衡,导致网络耗能较大,减少了网络生命周期;-从能量均衡角度提出了一种能量优化的Ad Hoc网络路由协议(EOARP协议),通过引入公共经济学中洛伦茨指数法来衡量网络的能耗均衡,结合节点通信繁忙程度、节点剩余能量等因素建立代价函数PEQ,选择剩余能量相对较高,通信繁忙程度较轻的路由链路,从而达到均衡网络的目的;仿真结果表明,EOARP协议在数据传输性能、能量均衡、以及网络节点剩余能量等方面指标均有较大改善,有效地延长了网络生命周期。The unbalanced node energy of traditional AD Hoc routing protocol causes alarger network energy,and it reduces network lifecycle.The article presents a energy optimization of Ad Hoc Network Routing Protocol（EOARP protocol）from the point of energy balance.Through the introduction of public economics Lorenz index to the average energy consumption of each node in the network,combined with the busy degree in communication and residual energy of nodes to establish cost functionPEQ.Select residual energy of the node relatively high,communication link routes is lesser busy,so as to achieve a energy-balanced network.As the simulation results EOARP routing protocol has improvement indexs such as data transmission performance,energy balance,and network node residual energy,so effectively prolongs the network life cycle.
