Adaptive Traffic-Aware Routing for Dynamic LEO Satellite Networks

Low Earth orbit (LEO) satellite networks require adaptive routing because satellite mobility, inter-satellite link availability, and traffic congestion change over time. This paper proposes a double deep Q-Network-based traffic-aware routing method for dynamic LEO satellite networks. The routing agent selects the next-...

Carbon-Aware Traffic Steering for TN-NTN Scenario via Graph Attention Reinforcement Learning

Sixth-generation (6G) wireless systems envision seamless coexistence between terrestrial networks (TNs) and non-terrestrial networks (NTNs), while the carbon footprint of dense radio access infrastructure has become a critical concern. This paper proposes carbon-aware traffic steering (CATS), a Near-RT RIC xApp for the...
