1、2014年1月北京航空航天大学学报January2014第40卷第1期JournalofBeijingUniversityofAeronauticsandAstronauticsV01.40No.1基于活动预测和能耗均衡的WSN路由算法汪成亮王强(重庆大学计算机学院,重庆400044)摘要:无线传感网络(WSN,WirelessSensorNetwork)中节点触发与数据传输往往会呈现出某种活动模式,基于活动模式特性提出了基于活动的节点分簇算法(AACP,Activity—AwareClusteringProtoc01),将网络中的传感器节
2、点分成多个活动簇,并通过对节点的历史触发数据进行分析,结合分簇结果对当前发生的活动进行预测.基于活动预测结果,综合能耗均衡、节点剩余能量、传输能耗等影响因素,提出了基于活动预测和能耗均衡的WSN路由算法(AEBRP,Activity—awareandEnergyBalancedRoutingProtoc01).仿真实验中与低功耗自适应集簇分层型协议(LEACH,LowEnergyAdaptiveClusteringHierarchy)、基于跟踪的动态节点分簇算法(HCMTT,HybridClusteringforMuhitargetTrac
