A Periodic Charging Planning for Joint Wireless Charging and Data Collection in Wireless Rechargeable Sensor Network

For the wireless charging equipment(WCE)with wireless charging and data collection in wireless rechargeable sensor network,we purpose a periodic charging planning of joint wireless charging and data collection,and prove that the problem is an NP-complete problem.Firstly,the influence of wireless charging and data collection on WCE path planning is analyzed,the sojourn time of WCE is calculated according to the current residual energy and data volume of the sensor node.Then we prove that the optimal solution is obtained under the premise of maximizing cycle time.Finally,the multi-population discrete fireworks Algorithm(MFWA)is designed to solve the problem.Network scenarios with the different number of nodes are generated in Matlab R2016a for simulation.The simulation results show that the performance of the MFWA algorithm is better than the DFWA algorithm.
