Hierarchical Q-Learning Routing Proposed for Multi-Charger Scheduling in Wireless Sensor Networks
A new arXiv preprint introduces HQARRF, a scheduling approach that combines hierarchical Q-learning with force-aware routing to coordinate multiple chargers in wireless rechargeable sensor networks. The method aims to balance sensor death risk, charger energy limits, travel costs, return-to-base feasibility and inter-charger coordination, which urgency-driven schedulers handle poorly. The work is categorized under machine learning research.
