On-Demand Mobile Energy Replenishment in Wireless Sensor Networks

Recently, adopting mobile energy chargers to replenish the energy supply of sensor nodes in Wireless Sensor Networks has gained increasing attention from the research community. Different from energy harvesting systems, the utilization of mobile energy chargers is able to provide more reliable energy supply than the dynamic energy harvested from the surrounding environment. While pioneering works on the mobile recharging problem mainly focus on the optimal offline path planning for the mobile chargers, in this paper, the authors aim to lay the theoretical foundation for the on-demand mobile charging problem, where individual sensor nodes request charging from the mobile charger when their energy runs low.
