摘要
低轨巨型星座网络抗毁性作为评估网络性能的关键指标而受到国内外学者的广泛关注。以低轨巨型星座网络抗毁性评估方法为研究对象,概述低轨巨型星座网络的基本架构和特点,归纳网络毁伤的威胁因素,分析在此架构下抗毁性研究所面临的难题。在此基础上,从图论、节点重要度和网络性能3个方面系统梳理了卫星网络抗毁性评估方法以及抗毁性优化策略,重点分析了现有抗毁性评估方法的特点及其在低轨巨型星座场景下的局限性。最后,从进一步增强低轨巨型星座网络抗毁性和优化评估策略的角度考虑,对未来潜在的研究方向进行了展望。
Low Earth orbit mega-constellation’s network invulnerability,as a key indicator for evaluating the performance of the networks,has received extensive attention from domestic and foreign scholars.Taking the invulnerability evaluation methods of low Earth orbit mega-constellation networks as the research object,the basic architecture and characteristics of low Earth orbit mega-constellation networks are introduced,the threat factors of network damage are summarized,and the difficulties faced by invulnerability research under this architecture are analyzed.Based on this,the constellation network invulnerability evaluation methods and optimization strategies are systematically sorted out from three aspects,namely,graph theory,node importance and network performance,with emphasis on analyzing the characteristics of the existing invulnerability evaluation methods and the limitations in the low Earth orbit mega-constellation scenario.Finally,from the perspective of further enhancing the network invulnerability of low Earth orbit mega-constellation and optimizing the evaluation strategy,the possible future research directions are envisioned.
