Decentralized MARL for SDN Ground Station Cluster Selection in LEO Constellations Under Stochastic Weather

A hybrid LEO-terrestrial architecture that integrates Software-Defined Networking ground station clusters with repeater-assisted reception and a structured fallback mechanism is proposed and results highlight the effectiveness of the proposed framework in enabling adaptive and delay-efficient control in next-generation LEO satellite systems.

The Impact of Demand Forecasting on Delay and Jitter in DVB-Based Beam-Hopping LEO Networks

It is demonstrated that when designing user demand forecasting solutions for practical LEO deployments, prioritizing system scalability may be more valuable than chasing minor accuracy enhancements, suggesting that when designing system scalability solutions, prioritizing system scalability may be more valuable than chasing minor accuracy enhancements.

Dynamic Controller Activation With Setup Penalty and Capacity Awareness in SDN-Enabled LEO Satellite Networks

Simulation results reveal that both setup penalties and controller activation thresholds are critical determinants of system behavior across both optimization-based and heuristic schemes, highlighting the necessity of jointly optimizing reassignment policies and controller activation strategies to support robust, low-latency, and resource-aware SDN architectures for large-scale LEO satellite constellations.
