中文摘要:
      基于磁耦合谐振的多节点充电技术为解决无线传感网络的健壮性问题提供了潜在的解决方法。为了减少充电设备的移动能耗,保证充电规划的可调度性,结合磁耦合谐振的充电效率,采用蜂窝网状结构将网络分割成若干充电区域,提出了基于移动充电设备的无线传感器网络充电调度算法。由于实际的移动设备能量通常有限,在每个充电周期内综合考虑移动设备能量、节点剩余能量等,提出了自适应动态算法以自动选择k个充电区域。规划充电路径时,采用实时性较好的弹性网络算法来满足网络节点的充电需求。仿真结果表明,充电设备能量的大小会直接影响网络的总能量与最小剩余能量,算法在设备能量有限时能够最大化网络的最小能量,延长网络的生命周期。
英文摘要:
      Multi-node charging technology based on magnetic resonance coupling provides a potential solution for the robustness of wireless sensor networks.Considering the charging efficiency of magnetic resonance coupling,cellularstructure was adopted to divide the network into several charging areas,and a charging scheduling algorithm in wireless sensor network based on mobile charger was proposed,so as to reduce the energy consumption of charging devices and guarantee schedulability of charging plans.A self-adaptive dynamic algorithm for automatically selecting k charging areaswas raised to comprehensively consider the energy of mobile charger,residual energy of nodes and other factors du-ring each charging period.When planning the route,elastic network algorithm with good timeliness was adopted to meet demands.The simulation results show that the energy of mobile charger has direct impact on total energy and minimum residual energy of networks.When the energy of mobile charger is limited,the proposed algorithm can maximize minimum network energy and extend the life cycle of the network.
