Efficient Algorithms for Characteristic Wireless Power Transfer Problems in Sensor Networks

In Wireless Rechargeable Sensor Networks, one or more special mobile entities (called the Mobile Chargers) traverse the network and wirelessly replenish the energy of sensor nodes, using wireless power transfer technology. In this paper, we present some state of the art algorithms that apply to characteristic problems in such networks, namely efficient use of wireless power transfer using i) one Mobile Charger, ii) multiple Mobile Chargers, iii) collaborative mobile charging.
