The cross entropy method for multi-disjoint energy route design of Wireless Power Transfer Network

Due to the limited power transmission distance range of power nodes based on the wireless power transfer technology, Wireless Power Transfer Network (WPTN) based on this technology is a promising novel pattern to broaden its applications and research field. To improve the power transfer efficiency and network reliability, best and optimal route design has become essential. In this paper, the routing problem of WPTN system is described, the mathematical model and its constraints are given in detail. In addition, the CE method is proposed to design multi-disjoint energy routes to satisfy solve these issues. Furthermore, the simulations and results are conducted on a 20-node WPTN system for designing the optimal routes design and verifying the effectiveness of the proposed scheme for the routing problem.
