A Mixed Mobile Charging Strategy in Rechargeable Wireless Sensor Networks

摘要

Based on the mobile charging scheduling strategy, the Mobile Charger (MC) complements the power supply for the sensor nodes. We proposed a Mixed Charging Schedule Algorithm (MCS) based on the periodic charging scheme and the on-demand charging scheme. We add a node's rate grouping mechanism to determine which nodes need to be recharged based on a dynamic threshold mechanism. Based on the periodic charging loops and the service station deployment mechanism, a charging loop is constructed according to guide the MC to wirelessly charge the sensor nodes. The proposed algorithm reduces the power consumption of the sensor network, improves the efficiency of MC mobile billing, and ensures the normal operation of the network.
