摘要:

随着信息通信技术的不断发展,人类对于扩大网络覆盖范围和降低通信时延的要求越来越高。低轨卫星网络是一种利用轨道高度较低的卫星构建的网络体系,具有覆盖范围广、通信时延低等优势。基于此,首先概述了低轨卫星网络的国内外发展现状及其组网所面临的挑战,进一步阐述了低轨卫星网络组网关键技术难点及建议,最后结合分布式、博弈论和人工智能等方法,对潜在可行的低轨卫星组网方案进行了探讨。

关键词: 低轨卫星组网技术, 人工智能, 博弈论, 6G空间互联网

Abstract:

With the continuous development of information and communication technology, the requirements for expanding network coverage and reducing communication delay are becoming higher and higher.Low earth orbit (LEO) satellite networking, as a network system constructed by satellites with low orbital altitudes, has the advantages of wide coverage and small communication delay.Firstly, the development status of LEO satellite network around and the challenges faced by LEO satellite networking were summarized.Then, the key technical difficulties and suggestions of LEO satellite networking were described.Finally, some potentially feasible LEO satellite networking schemes were discussed, combined with the theory and methods of distribution, game and artificial intelligence.

Key words: LEO satellite networking technology, artificial intelligence, game theory, 6G space Internet
