摘　　要：自组网是由兼做路由器的移动节点组成的移动无线网络,不依靠通信基础设施。本文提出了一个工作于物理层和MAC层之上、网络层之下的基于自组网的节能协作算法,其核心思想是构造虚拟主干网,使位于虚拟主干网外的节点工作于休眠状态,从而减少电源消耗。A Mobile Ad Hoc Network( MANET) is a type of mobile wireless networks composed of many mobile nodes. Each node is a router as well asa communication end-point. MANET does not depend on communication infrastructures. This paper presents a power-saving coordination algorithm in MANET above the physical and MAC layers and under the network layer. Its core is to construct a virtul backbone so that nodes outside the virtul backbone keep sleeping and saving power.
