동적 저궤도 위성 네트워크를 위한 Dueling DQN 기반 라우팅 기법 = Dueling DQN-based Routing for Dynamic LEO Satellite Networks

다국어 초록 (Multilingual Abstract)

This paper deals with a routing algorithm which can find the best communication route to a desired point considering disconnected links in the LEO (low earth orbit) satellite networks. If the LEO satellite networks are dynamic, the number and distribution of the disconnected links are varying, which makes the routing problem challenging. To solve the problem, in this paper, we propose a routing method based on Dueling DQN which is one of the reinforcement learning algorithms. The proposed method was successfully conducted and verified by showing improved performance by reducing convergence times and converging more stably compared to other existing reinforcement learning-based routing algorithms.
