In Figure (b), we discuss the impact of the moving speed of mobile chargers on the performance of different algorithms in a network with 100 sensor nodes. Changing mobile charger speed from 1m/s to 5m/s enhances the sensor node survival rate by approximately 5% in TSPC-DRL. However, increasing the movement speed of mobile chargers does not significantly improve the node survival rate for other algorithms. Table III reveals that despite no improvement in energy efficiency with increased charger speed, TSPC-DRL maintains superior energy efficiency over other algorithms.
