为了使能量受限的无线网络寿命更大化,提出了MANET中基于能量约束的机会路由(ECOR).根据节点的能量消耗模型(NECM)建立了候选节点等待时间函数(WTF);提出了基于能量的节点转发候选集选择策略(ECETX),综合考虑每个节点的归一化能量值(PI)与链路状况来产生投递矩阵(delivery matrix),以确定转发候选集中节点的优先级;利用以上策略设计了基于能量约束的机会路由(ECOR).仿真实验表明,提出的ECOR比ExOR的网络寿命有明显提高,平均增长55%～70%左右,吞吐量也有15%～23%的提高.

This paper proposed an opportunistic routing based on energy-constrainting in mobile Ad hoc networks to maximize the life of energy-constrainting wirless networks.Firstly, introduced the node energy-consuming model(NECM),and constructed the waiting time function(WTF).Then proposed the strategy for selecting forwarding candidates set based on metric named ECETX which consider both the unitary energy(PI) and the link state in order to build the delivery matrix,and then selected the nodes' priorities which in forwarding candidates set.At last,designed an energy-constrainting opportunistic routing(ECOR) based on all of the above strategies.The simulation results show that the life of the network using ECOR is longer than using ExOR,increase by 60～70 percents in average,and the throughput increase by about 15～23 percents.
