Destination Point Scheduling Method for Mobile Charger in Wireless Rechargeable Sensor Networks

摘要

In Wireless Rechargeable Sensor Networks(WRSN), the sensor is responsible for sensing the environment and creating sensing data; the mobile charger (MC) plays a role in recharging the sensors and collecting sensing data into the sink. Sensor nodes can obtain power from the wireless charger to recharge the battery in WRSN and help it operate sustainably. This process allows the sensor battery to be charged when needed and maintains the continuous operation of the network because the MC can provide a reliable and stable source for the sensor nodes in the limited charge range. Based on this technique, we propose a new destination scheduling method for the MC. In this method, we use the maximum energy point algorithm (MEPA) as an energy charging point to charge for sensor nodes. We conduct some simulations to investigate the outcome and effectiveness in compare with the previous method in term of energy saving. The simulation results show that our proposed method brings positive performance with improved rates of charging sensor nodes, and less time consumption than previous method.
