A Per-Action Structured D3QN-Based Hierarchical Routing Algorithm for LEO Mega-Constellation Networks
This paper fuses deterministic inter-domain planning with DRL-based intra-domain forwarding in a single hierarchical framework and develops a greedy–beam–Dijkstra fallback ladder that guarantees reachability whenever the subgraph stays connected.
