Joint Trajectory Design and Resource Allocation for QoS-Aware Emergency Data Collection in UAV-Assisted WPCNs: A Hierarchical DRL Approach

Unmanned aerial vehicle (UAV)-assisted wireless-powered communication networks (WPCNs) have emerged as a promising solution for energy-constrained Industrial Internet of Things systems, where ground sensor nodes are often deployed in harsh and hard-to-reach environments. However, efficient UAV-assisted data collection...
