On-demand energy replenishment for sensor networks via wireless energy transfer

Xu, Wenzheng; Liang, Weifa; Ren, Xiaojiang (Richard); Lin, Xiaola


In this paper, we study the use of a wireless charging vehicle (WCV) to replenish energy to sensors in a wireless sensor network so that none of the sensors will run out of its energy, where sensor batteries can be recharged. Specifically, we first propose a flexible on-demand sensor energy charging paradigm that decouples sensor energy replenishment and data collection into separate activities. We then formulate an optimization problem of wireless charging with an aim to maximize the ratio of...[Show more]
