摘    要:网络感知覆盖和能量消耗是无线传感器网络的两个核心问题,两者密切相关.网络覆盖决定了无线传感器网络对物理世界的监测能力,反映了网络所能提供的"感知"服务质量,能量消耗则决定了无线传感器网络的生存时间.提出了一种节点能量异构自适应的无线传感网络覆盖控制协议HEAP(a Heterogeneous Energy Adaptive controlcoverage Protocol),HEAP采用基于节点分层成簇的思想,根据节点邻居平均能量与自身剩余能量等参数竞选活动节点.理论分析与模拟实验表明,HEAP协议不但能够提供高质量的网络覆盖率,而且可以有效地适应于节点能量异构的网络应用场景,并且减少活动节点选取过程中的控制消息开销.

关 键 词:无线传感网络  能量异构  覆盖控制

Abstract:Sensing coverage and energy consumption are two primary issues in wireless sensor networks.Sensing cove-rage is closely related to network energy consumption.The performance of a sensor network depends to a large extent on the sensing coverage,and its lifetime is determined by its energy consumption.A Heterogeneous Energy Adaptive coverage control Protocol for wireless sensor networks(HEAP) was proposed.Adopting the hierarchical clustering idea,HEAP elects the working nodes based on the average residual ene...
Keywords:Wireless sensor network  Heterogeneous energy  Coverage control
