摘要
针对恶劣环境下无人值守的无线传感器网络能量受限特性,提出一种时间和能量混合拓扑维护策略,以达到实现节点能量均衡的目的.将拓扑控制分为网络初始化阶段、拓扑构建阶段和拓扑维护阶段,在随机部署和虚拟骨干网络构建的前提下,确立了能量和时间作为拓扑维护触发条件的合理性.仿真表明,所提出的混合拓扑维护策略使网络生命周期提升了 44.6%,90%覆盖率结束时间增加了 1.4 倍,为无线传感器网络的节能部署提供了参考.
Abstract
A hybrid topology maintenance strategy based on time and energy was proposed to achieve node ener-gy balance in response to the limited energy characteristics of unattended wireless sensor networks in harsh envi-ronments.The topology control was divided into the network initialization phase,topology construction phase,and topology maintenance phase.Under the premise of random deployment and virtual backbone network con-struction,the rationality of using energy and time as triggering conditions for topology maintenance was estab-lished.Simulation results showed that the proposed hybrid topology maintenance strategy could improve the net-work lifetime by 44.6%,and the ending time of 90%coverage increases by 1.4 times,which provided a guid-ance for energy-saving deployment of wireless sensor networks.
