摘要/Abstract

摘要：

利用不同轨道卫星的特点组建更高效的多层卫星网络，近年来成为卫星网络研究的热点。传统卫星网络接入方法己经难以满足多层卫星网络低时延、灵活随遇接入的需求，设计高效的多层卫星网络随机动态接入协议迫在眉睫。首先对传统卫星网络接入技术进行总结，梳理卫星网络随机接入协议的发展脉络；然后针对地面站接入卫星以及多层卫星网络星间接入两种不同场景分别提出不同的低时延接入方法，为未来多层卫星网络动态接入技术的发展提供参考。

关键词: 多层卫星网络, 低时延, 动态接入

Abstract:

Using the characteristics of satellites in diff erent orbits to build a more effi cient multilayer satellite network has become a hotspot in satellite network research in recent years.Traditional satellite network access methods have been unable to meet the needs of multilayer satellite networks with low latency and fl exible access, so it is urgent to design an effi cient random dynamic access protocol for multilayer satellite networks.This paper fi rst summarized the traditional satellite network access technology, clarifi ed the development context of the satellite network random access protocol, and then proposed diff erent low latency for the two diff erent scenarios of ground station access to satellite and multilayer satellite network intersatellite access.The access method could provided a reference for the development of the dynamic access technology of the multilayer satellite network in the future.

Key words: multilayer satellite network, low latency, dynamic access
