摘　　要：针对Ad Hoc网络中源节点和目的节点在已建立的路径上长时间发送大量数据包,使路径节点耗能过快,从而导致部分节点电池能量过早耗尽的现象,提出了IM_AODV算法。该算法对路径节点能量的消耗情况进行实时监测,当路径消耗的能量超过阀值时重建路由。实验结果表明I,M_AODV算法通过节点能量的均衡消耗,提高了整个网络的生存时间。Aimed at the issue that some nodes of specific path established may exhaust their power quickly by transferring huge number of packets for the same pair of source and destination, an improved AODV algorithm, IM_AODV, is proposed. In IM_AODV, the new route is re-established when the real-time monitored energy consumption of current path exceeds the threshold. Experimental results show that IM_AODV actually produces longer lifetime of network by balancing energy consumption of nodes.
