Effect of Ground Stations in Satellite Networks for Task Distribution in Centralized and Decentralized Approaches

This thesis explores the optimization of satellite constellations to enhance ground station coverage and task distribution efficiency. By comparing centralized, decentralized, and partially centralized network configurations, the research aims to determine the optimal setup for minimizing total time delay and improving performance metrics. This study investigates how ground stations influence task distribution and evaluates the benefits of adding one or more ground stations to enhance network performance. By evaluating 44 optimization algorithms across two satellite configurations, the study identifies the top algorithms for maximizing coverage at the lowest altitude. The results demonstrate that an optimized satellite configuration significantly enhances coverage and reduces latency. Increasing ground station density markedly improves performance in centralized and partially centralized networks, though less so in decentralized configurations. The inclusion of multiple ground stations shows significant improvements in network efficiency, highlighting the benefits of both centralized and decentralized approaches. Additional central nodes show nuanced impacts on time delay and post-capture time, indicating areas for further refinement. The link budget analysis confirms that effective communication can be maintained in optimized configurations, with potential improvements through enhanced error correction methods. This study provides valuable insights into optimizing satellite network design, contributing to more efficient and reliable space communication systems.     «
