Abstract
Wireless sensor networks are bounded by their limited energy supply. Recharging batteries energy from distance by the wireless energy transferring technique will, to certain extent, solve the energy problem of the whole network. During this discussion, we studied the data routing and the recharging schemes for rechargeable wireless sensor nodes deployed in 3-dimensional spaces. According to our objective of maximizing the time ratio of recharging device staying at the service station, we formulate the continuous model, the simplified continuous model and the (T + 1)-phased discrete model. Simulations show that rechargeable wireless sensor networks will keep on working with the help of the amount of energy obtained from recharging devices. Our solution shows better performance than genetic algorithm both in time ratio and time complexity.
