Toward the Age in Forwarding: A Deep Reinforcement Learning Enabled Routing Mechanism for Large-Scale Satellite Networks via Spatial-Temporal Graph Neural Networks

In large-scale satellite networks, end-to-end data delivery confronts long propagation latency and dynamical connectivity, heavily challenging current routing strategies due to the time-changing topology. For the tasks with high timeliness requirements, especially, it will cause obviously low freshn...
