摘要 针对无线传感器网络(WSN)中的"路由热点"问题,提出了在簇头移动的前提下基于事件驱动的基站簇头混合移动策略BS-CH HMS(base station-cluster head hybrid mobile strategy).该策略根据CH(cluster head)移动时的能量损耗确定CH的移动轨迹,制定基站的协作移动策略.理论分析和仿真结果表明:采用所提出的混合移动策略,簇头的能量消耗比采用单独移动CH的路由策略节省30%,提高了移动簇头的能量效率,延长了网络的生命周期. In order to investigate the route hotspot problem in wireless sensor network（WSN）,a BS-CH（base station-cluster head） hybrid mobile strategy based on event-driven,BS-CH HMS（base station-cluster head hybrid mobile strategy）,was proposed on the assumption of CH mobility.In this strategy,the mobile path of CH（cluster head） is determined and the cooperative mobile strategy of the base station is designed in light of the energy consumption of moving CH.The theoretical analysis and simulation results show that using the BS-CH HMS compared with using a single CH mobile strategy,CH energy consumption is decreased by 30% to enhance the energy efficiency of moving CH and prolong the lifetime of WSN.
