On Renewable Sensor Networks With Wireless Energy Transfer: The Multi-Node Case

Wireless energy transfer based on magnetic resonant coupling is a promising technology to replenish energy to sensor nodes in a Wireless Sensor Network (WSN). However, charging sensor node one at a time poses a serious scalability problem. Recent advances in magnetic resonant coupling shows that multiple nodes can be charged at the same time. In this paper, the authors exploit this multi-node wireless energy transfer technology to address energy issue in a WSN. They consider a Wireless Charging Vehicle (WCV) periodically traveling inside a WSN and charging sensor nodes wirelessly. They propose a cellular structure that partitions the two-dimensional plane into adjacent hexagonal cells.
