摘　　要：针对移动自组网(MANET)大规模组网时普通路由算法性能明显下降的问题,利用分而治之的思想,提出了一种将AODV和时延容忍网络中喷雾等待路由相融合的路由方案ADHR,即在反应式路由扩展环区域内仍实施普通AODV路由策略,但是当源与目的节点距离超过扩展环半径时,自动地转入DTN的喷雾等待路由,使得MANET网络规模扩大时性能保持相对稳定。ONE仿真平台实验结果表明,在大规模网络环境下,ADHR的分组投递率等主要网络性能要优于纯AODV和喷雾等待路由。As the performance of large scale MANET with common Route method falls obviously,a novel ADHR route strategy which integrates AODV and Spay Waiter protocols was proposed.In the range of AODV search extending ring,it still executes common AODV route protocol.But out of the range,the source node and the destination are too far away from each other,the Spay Waiter protocol begins to work.By this way,the performance of large scale MANET becomes stable.The ONE experiment result shows that the main performance of ADHR（such as delivery rate） is better than AODV and Spay Waiter route protocols.
