Distributed routing and scalable control for wide-area connectivity
Distributed routing and scalable control for wide-area connectivity
LEO satellite networks are becoming a key infrastructure for future wide-area and global connectivity. Their low orbital altitude enables reduced latency compared with traditional satellite systems, while large constellations provide broad coverage and flexible connectivity.
The visualization below illustrates dynamic packet forwarding and route evolution in a LEO satellite network simulator. It highlights how connectivity changes over time as satellites move and how routing decisions adapt to topology changes and communication constraints.
Routing in LEO satellite networks is fundamentally different from routing in static terrestrial networks. Satellite motion continuously changes network topology, which affects path availability, hop count, delay, and link usage.
In addition, large satellite constellations require scalable routing mechanisms that can adapt quickly without excessive control overhead. Reliable communication also depends on handling link failures, balancing traffic, and coordinating satellite and ground segments efficiently.
Distributed Routing
I study distributed routing strategies for large LEO constellations, with emphasis on scalable path selection and end-to-end connectivity under dynamic topology changes.
Link Failure Recovery
My research addresses routing robustness under link failures by designing detour and recovery mechanisms that maintain connectivity while limiting rerouting overhead.
Satellite-Grounded Ingerated Networks
I also investigate routing and service planning in satellite-ground integrated networks, where both orbital and terrestrial resources must be coordinated efficiently.
Scalable Network Modeling and Simulation
To validate routing strategies, I develop simulation and visualization frameworks for large LEO constellations, capturing topology evolution, packet forwarding, and end-to-end routing behavior.
