摘　　要：针对传统电池供电系统能量有限问题,提出一种大范围无线可充电传感器网络(WRSNs)的数据路由和无线充电算法.以无线感知识别平台为基础,利用等边三角形的强覆盖性,并综合考虑网络路由协议和无线充电器特性对节点能量的影响,提出一种基于六边形路径的动态无线充电算法(IJRC_HP).算法包括两部分:依据充电器特性设计数据路由方法,使得能量接收功率高的节点承担更多的通信任务;依据该路由的特点设计充电方案,为能耗速度快的节点分配更多的充电时间.与等边三角形算法(TRIANGLE)、GRID算法进行仿真对比,实验结果表明,IJRC_HP算法在网络寿命提升、能量均衡、充电器移动效率和节点平均充电延时等方面具有优越性.For the energy constraint problems in traditional battery-powered systems, a data routing strategy and wireless charging algorithm for large-scale WRSNs is proposed. Based on the the industrial wireless identification and sensing platform, considering the influence of the routing protocols and the characteristics of wireless charger, a dynamic wireless charging algorithm based on hexagon path, namely improved joint routing and charging algorithm based on hexagon path（IJRC_HP）, is proposed by taking advantage of the strong coverage of equilateral triangle. The IJRC_HP algorithm contains two parts： a data routing strategy is designed in accordance with the characteristics of a wireless charger to make the nodes with high energy receiving power take more communication tasks; more charging time is allocated for the nodes with more energy consumption according to the characteristics of the routing strategy. Comparing with the TRIANGLE algorithm and GRID algorithm, simulation results demonstrate that the proposed IJRC_HP algorithm has a better performance in terms of network lifetime, energy balance, moving efficiency of wireless charger and average charging latency.
