In the current research of wireless rechargeable sensor networks
the charging planning problem often considers a single goal only
without considering the impact of the energy hole problem on the path planning of the wireless harging equipment(WCE) and the performance of the entire network. Based on the charging time window and penalty function
to maximize the energy utilization of WCE in the network and minimize the node penalty value
a multi-objective path planning model with time window is proposed to optimize the charging time of WCE to nodes and improve the energy utilization of WCE. To solve the multi-objective optimization problem
based on the multi-objective continuous firework algorithm
a multi-objective discrete firework algorithm is proposed
which speeds up the convergence speed and avoids falling into the local optimum through the firework explosion operation. The simulation results show that compared with the traditional algorithm
the Pareto optimal solution obtained by the algorithm proposed in this paper has at least 22.5% improvement in the distribution uniformity and 14.5% improvement in the performance of distribution range.
