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 char...
