Review of Digital Twin Based Satellite Network Mobile Edge Computing

With the rapid development of communication technology,satellite communication has become a crucial part of modern information and communication landscape.Satellite networks,with their extensive coverage,can provide ubiquitous low-latency services to users worldwide.However,the construction of satellite networks still faces significant challenges,such as high satellite design costs,the risks associated with launches,and the expensive testing and maintenance of satellite networks.The rise ofdigi-tal twin(DT) technology presents a perfect synergy with satellite networks,offering powerful data support and decision-making tools for satellite network operations.This paper reviews the research progress on DT-based mobile edge computing in satellite networks.It begins by introducing the limitations of terrestrial base station communications,which leads to the discussion of satellite network applications.Then,the composition of satellite networks,satellite classifications,and the concept of satellite edge computing are thoroughly explained.Subsequently,DT technology is introduced,with a focus on the DT-based satellite edge computing platform and DT-based mobile edge computing algorithms for satellite networks.Finally,this paper summarizes the exis-ting issues in current research and outlines future development directions.
