This document proposes a solution for multi-node remote energy charging in wireless sensor networks. A wireless charging vehicle periodically travels within the sensor network and remotely charges sensor nodes. The proposed solution divides the area into hexagonal cells based on the charging range of the vehicle. Numerical results show that the cell structure approach can effectively address the energy replenishment needs of the sensor network over time. The solution formulates the problem as a mixed integer nonlinear program to determine the optimal travel path that minimizes total energy usage.
