摘　　要：针对由智能移动设备组成的无线自组网的能量受限问题,提出了一种基于应用感知的跨层节能路由机制(ACER)。通过使用应用程序监测模块和剩余能量监测模块感知节点的能量消耗特征。数据链路层采用链路稳定性监测模块监测网络路径上链路的稳定性。提出的ACER路由机制采用跨层设计的思想,综合利用网络层拓扑信息、应用层应用感知信息和链路稳定性信息进行路由决策。通过使用NS实验平台对提出的方案进行仿真并与相关的经典路由算法进行分析比较,仿真结果表明所提出的路由方案能有效提高网络的能量使用效率和性能。An application-aware cross-layer energy-efficient routing scheme(ACER) was presented to minimize the effect of supply of terminals in ad hoc network composed of smart mobile devices.Features of energy consumption were sensed by application aware energy model with the application monitor and the remaining energy monitor.Stability of network path was monitored by link stability monitoring module in Data link layer.As the scheme used the idea of cross-layer design,network topology information,application-aware information in application layer and link-stability were utilized synthetically to make routing decisions in network layer.Simulations were carried out on NS2 platform.The results show that,in the same simulation environment,comparing to other routing protocols,the routing scheme performs more effectively on enhancing energy efficiency,increasing the performance of the network.
