无线可充电传感器网络（WRSNs）中现有的充电方案缺乏可扩展性评估，降低了充电效率，导致节点耗尽。我们提出了一个最优路径规划收费计划，即OPPC，按需收费架构。OPPC评估充电使命的可执行性，这使得充电调度可预测。它提供了一个最佳的充电路径，最大限度地提高充电效率。当面临不可重传的充电使命时，提出了一种节点丢弃算法来实现重传。仿真实验表明，OPPC在充电成功率和充电效率方面都有较好的性能。
The lack of schedulability evaluation of previous charging schemes in wireless rechargeable sensor networks (WRSNs) degrades the charging efficiency, leading to node exhaustion. We propose an Optimal Path Planning Charging scheme, namely OPPC, for the on-demand charging architecture. OPPC evaluates the schedulability of a charging mission, which makes charging scheduling predictable. It provides an optimal charging path which maximizes charging efficiency. When confronted with a non-schedulable charging mission, a node discarding algorithm is developed to enable the schedulability. Experimental simulations demonstrate that OPPC can achieve better performance in successful charging rate as well as charging efficiency.
