摘　　要：无线可充电传感器网络中,节点在不同方向的能量接收能力是不同的,现有的充电策略很少考虑节点能量接收能力的各向异性。本文研究基于接收能力各向异性的移动充电策略,提出一种基于有向能量接收的高效充电算法(CderM)。先建立节点充电区域模型衡量节点的异向能量接收能力。再根据节点部署情况,优化充电部署,增加MC的充电覆盖区域,增大网络充电覆盖率。最后,采用启发式策略优化节点能量接收方向,最大化节点的有向能量接收能力,实现高效率充电。仿真结果表明CderM算法增大了网络充电覆盖率,提高了能量补充效率。In wireless rechargeable sensor networks(WRSN),the energy receiving ability of nodes is different in different directions,and the anisotropy of energy receiving ability of nodes is seldom considered in the existing charging strategies.This paper studies the mobile charging strategy based on the directional power-receiving model,and proposes an effective charging scheme based on directional power-receiving(CderM).Firstly,the node charging area model is established to measure the power-receiving ability of the node.Then according to the node deployment,it optimizes the charging deployment,increases the charging coverage area of mobile charger(MC).Finally,it optimizes the node power-receiving direction in heuristic method to maximize the power-receiving capacity of the node,so as to achieve high efficiency charging.The simulation results show that the CderM algorithm increases the network charging coverage and improves the efficiency of energy replenishment.
