摘　　要：低轨道分布式卫星网络作为6G通信技术的重要组成部分,可以实现高速传输和低延时的通信,可以满足6G通信技术的高速率和低延时的需求。针对低轨道分布式卫星网络的组网方法进行了研究,对卫星网络的路由算法进行了归纳总结,提出一种基于带宽和延迟联合的路由选择算法,并实现了三种不同的路由选择算法,发现各算法性能差异明显。实验结果表明基于带宽和延迟联合算法在选择最佳路径的同时,能够更好地平衡网络的负载和减小时延,提高卫星网络的传输效率。As an important component of 6G communication technology,the Low Earth Orbit(LEO)distributed satellite network can achieve high-speed transmission and low-latency communication,and meet the high-speed and low-latency requirements of 6G communication technology.This paper addresses the networking method of LEO distributed satellite networks.The routing algorithms of the satellite network are summarized.A joint routing algorithm based on bandwidth and delay is proposed,and three different routing algorithms are implemented to select.It is found that the performance of each algorithm is obviously different.The experimental results show that the joint algorithm based on bandwidth and delay can better balance the network load and reduce the delay while selecting the best path,and improve the transmission efficiency of satellite network.
