A Multi-Agent Hierarchical Group-Based Handover Strategy for Massive Users in LEO Satellite Networks

In this letter, a multi-agent hierarchical group-based handover strategy is proposed for low Earth orbit (LEO) satellite networks, leveraging the Ward hierarchical clustering-enhanced dueling double deep Q-network (WHC-D3QN) strategy to reduce signaling overhead and enhance throughput. Specifically, the scheme first cl...

Agentic and Embodied UAV Relays for Satellite–Aerial Networking: End-to-End Latency-Aware Optimization

Integrated satellite–aerial networks (ISANs) are emerging as a promising architecture that combines high-throughput inter-satellite transmission with the agility of uncrewed aerial vehicles (UAVs) to support flexible and low-latency traffic delivery. Owing to the inherently uneven traffic distribution in the satellite...

Distributed Routing for LEO Satellite Networks: A Multi-Agent Deep Reinforcement Learning Approach With State Information Lag

Multi-agent deep reinforcement learning (MADRL) offers a promising solution for routing in low Earth orbit (LEO) satellite networks. However, large inter-satellite propagation delays lead to severe state information lag in agent interactions, giving rise to decision biases and degraded routing timeliness. To this end,...
