基于DQN的低轨卫星网络多目标智能路由算法
Multi-Objective Intelligent Routing Algorithm for LEO Satellite Networks Based on DQN
摘要
Abstract
In recent years,LEO satellite networks have developed rapidly and are widely used in global communication and internet ac-cess.This paper first summarized the current development status of LEO networks and the main LEO network routing algorithms.At the same time,aimed at the challenges of single optimization objectives,slow convergence speed,and difficulty in optimizing indica-tors such as delay and packet loss,this paper proposed a multi-objective intelligent routing algorithm based on deep Q-network(DQN).With the designed DQN multi-objective reward function,it realized the optimization of delay,packet loss,load balancing.Regarding de-lay,the proposed algorithm is superior to the Shortest Path First(SPF)algorithm.In terms of traffic distribution index and packet loss rate,the performances of the proposed algorithm are improved by more than 14%and 10%compared with the SPF and Dijkstra algo-rithms respectively.In addition,this paper illustrated the application methods of the proposed intelligent routing algorithm in various scenarios.关键词
