摘　　要：实现QoS路由是保证在移动Ad Hoc网络中进行高效的多媒体业务传输的关键,然而现有的QoS路由协议很少考虑节能的问题,对此提出了一种基于能量管理的QoS路由协议。其能量管理机制采用跨层设计的思想,通过通信事件和定时器来激发移动节点在节能模式和活跃模式之间切换以达到节约能耗的效果。仿真结果表明,该协议显著地延长了网络生存时间,具有较好的性能。Realizing QoS routing is a key point to guarantee effective transportation of multimedia service in mobile Ad Hoc network. However, few QoS routing protocol considers the issue of energy conversation. Hence, a QoS routing protocol based on power management is proposed. Its power management mechanism introduced idea of cross-layer design and achieved low energy consumption through transitions between power-save mode and active mode of mobile nodes triggered by communication events and timer. Simulation results show that such protocol remarkably increases the life-span of network and has high performance.
