摘　　要：与传统网络相比,无线Ad Hoc网络(以下简称为Ad Hoc网络)节点能量往往有限,同时在许多应用场合得不到及时的补充。文中简要分析了Ad Hoc网络中能量优化路由的研究现状,指出了在当前网络环境下能量优化需要进一步研究的问题。针对Ad Hoc网络中移动节点能量有限的问题,综合考虑节点剩余能量和节点能量消耗速率两方面因素,提出了一种基于节点生存时间的路由算法MRL.通过估算节点使用寿命,选择生存时间最长的路由,以此来均衡移动网络中各节点的能量。Compared with traditional networks, wireless ad hoc networks （hereinafter termed as ad hoc networks） are energy-constrained in many applications, because the nodes are powered by batteries and batteries recharging is infeasible. In this paper, the research status on energy-optimized ad hoc routing is analyzed. Some critical issues involved in the ad hoc networks energy optimization in the current network environment needed further research on are pointed out. Focused on the energy limitation of mobile nodes in Ad hoc network,both sides of the remaining nodes energy and the velocity of nodes energy consumption are considered. On that base a new Ad Hoc routing algorithm MRL based on time to live of nodes is proposed.Through calculating the sevice life of nodes,one routing with maximum life of nodes could be selected. Therefore the balance of the energy of nodes in Ad hoc network is achieved.
