摘　　要：移动自组网络是一种灵活的不依赖于固定基础设施的新型无线网络,生存性极强,且创建与移动极为方便的特点,使之弥补了蜂窝系统与有线网络的不足,在许多特殊情况下有着不可替代的作用。文中通过对Ad Hoc网络中OLSR链路状态路由协议的分析,在OLSR协议的基础上,通过修改OLSR协议单一的跳数度量方式,将节点的剩余能量作为度量的一个因素,并计算最终路由信息。通过仿真,证明该算法提高了分组投递的可靠性,减少了端到端时延,提高了网络的吞吐量。Mobile Ad Hoc network is a kind of agile new wireless network does not depend on fixed infrastructure, with strong survivability, convenient creating and moving, to make up for the shortage of the cellular system and the cable network, in many special cases having the effect that cannot replace. Analyze the Link State Rout Protocol in Ad Hoc, on the basis of it, through the modification of OLSR protocol single hop count measure way ,take the rest of the node energy as a factor of measurement,and compute the final routing information. Through the simulation show that this algorithm improves the packet delivery reliability, reduces the end-to-end delay and increases the network throughput.
