Abstract

The wireless sensor networks' (WSNs') sensor nodes' (SNs') limited energy is a crucial factor to take into account since it can result in data loss or even the entire network failing. In order to address energy shortages or meet energy demands, wireless power transfer (WPT) was introduced as a means to overcome this problem. With WPT, SNs can have their battery power restored by recharging them through one or more chargers, thereby extending their lifespan. Planning a charging schedule for a mobile charger (MC) is an NP-hard issue. As part of our research, we present a priority-based charging scheduling algorithm that can be used on wireless rechargeable sensor networks (WRSNs). The suggested algorithm primarily considers the SNs' remaining energy and the timing of charging requests. To demonstrate the suggested algorithm's higher performance, we simulate it and compare the results with those of other commonly used approaches.
