Abstract
The wireless rechargeable sensor network mainly consists of a data processing unit, a sensor (data acquisition unit), and a mobile charger (energy supply unit). For the wireless rechargeable sensor network to work properly, the mobile charger needs to charge the sensors periodically through the route given by the data processing unit, but the mobile charger incurs unnecessary energy loss on the charging journey. This paper discusses the problem of route planning and the minimum capacity of sensor batteries for single versus multiple mobile chargers. First, the TSP and MTSP problems of minimum energy consumption of mobile chargers over the distance are solved by modeling them with Monte Carlo optimization simulated annealing algorithm, and improved genetic algorithm, respectively. Then, the problem is further transformed into a linear programming and multi-objective optimization model to solve for the minimum capacity of the battery. In addition, computational experiments using the LKH algorithm and CA learning methods are conducted in this paper to propose optimization scenarios for the route planning model.
