Research on Energy Supplement Strategy of Wireless Rechargeable Sensor Network

为均衡网络能耗,及时为可充电无线传感器网络中能量较低的节点补充能量,本文提出一种基于非均匀分簇的多跳能量补充算法。该算采用非均匀分簇的多跳路由协议,每次充电前基站根据本文提出的剩余时间与地理位置联合优先权算法,计算出各簇的优先值后规划最优充电路径。仿真实验结果表明,本算法与其他算法相比有较好的扩展性,能有效均衡网络能耗并及时为节点充电。

In order to balance the energy consumption of the network and timely replenish energy for the lower energy nodes in the rechargeable wireless sensor network,this paper proposes a multi-hop energy replenishment algorithm based on non-uniform clustering.This calculation uses a non-uniform clustering multi-hop routing protocol.Before each charge,the base station plans the optimal charging path after calculating the priority value of each cluster according to the remaining time and geographic location joint priority algorithm proposed in this paper.The simulation experiment results show that this algorithm has better scalability than other algorithms,can effectively balance the network energy consumption and charge the nodes in time.
