摘　　要：移动Ad Hoc网络广泛用于各种条件比较艰苦的环境中,常用的AODV协议在设计之初没有考虑节点的能量问题,使用时可能导致某一关键节点的能量急剧下降而使链路失效。针对这一情况,新设计的IAODV协议在源节点新增了一条备用路径,各节点在周期性广播HELLO消息时主动报告节点的能量状态,在转发路由请求消息前,将节点的剩余能量和当前负载考虑进去,改进路由请求转发机制,通过这些方式,加强了整个协议的网络平衡和协调性,节省了单个节点的能量。在NS2这个模拟平台下,通过仿真可知IAODV协议平均端到端时延更短,丢包率更低。Mobile Ad Hoc network is widely used in all kinds of harsh environment, at the beginning ot aeslgn, the commonly used AODV protocols didn＇t consider the energy problems of a node. When in use, could lead to a sharp decline in a key node energy and make the link failure. In view of this situation, the IAODV protocol, new designed, add a alternate path in the source node, When periodic broadcasting Hello message, each node to report their energy state, before forwarding the route request message, Considering the node＇s residual energy and current load, improve the route request forwarding mechanism, By these measures, strengthen the network balance and coordination, the single node energy has been saved. In the NS2 simulation platform, the simulation shows that the IAODV protocol＇s average end-to-end delay is shorter, the lost packet rate is lower.
