저궤도 위성 네트워크에서 배터리 방전 심도 최소화하기 위한 에너지 및 부하 인지 라우팅

초록

This paper proposes an energy and traffic load aware routing scheme for Low Earth Orbit (LEO) satellite networks, aiming to maximize the remaining battery levels of the satellites. It predicts available battery levels by considering both eclipse status and recent transmission history, and selects the optimal path from k-shortest candidates based on the expected energy consumption during the eclipse period. In particular, incorporating recent transmission and reception logs improves enhances load balancing by excluding heavily utilized satellites from path selection. Our method, which utilizes predictable eclipse information instead of relying on real-time battery data from all satellites, offers high feasibility. Performance evaluations using the custom-developed simulator confirmed that the proposed scheme outperforms compared methods in terms of minimum residual battery level and load balancing.
