Poster: A Routing Algorithm for Enhancing TCP Performance in LEO Satellite Networks

The rapid changes in network topology caused by the mobility of LEO satellites lead to inter-satellite link (ISL) disconnections. Accordingly, such disconnections will degrade TCP throughput of LEO services. In this paper, we propose a routing algorithm for LEO satellite networks that reduces path c...

Summary:The rapid changes in network topology caused by the mobility of LEO satellites lead to inter-satellite link (ISL) disconnections. Accordingly, such disconnections will degrade TCP throughput of LEO services. In this paper, we propose a routing algorithm for LEO satellite networks that reduces path changes by avoiding ISLs prone to disconnection. The simulation results demonstrate that the proposed algorithm achieves higher TCP throughput compared to the benchmark methods.
