Space Cloud-Fog Computing: Architecture, Application and Challenge

With the development of space technology, it is an inevitable trend to build a flexible and efficient computing system for space-based information network. Traditional limited computing in single satellite cannot meet the increasing needs and cannot make effective use of the resources. This paper proposes a space-based cloud-fog computing architecture, which applies cloud-fog computing system to the space-based information network, and then we introduce the deployment of the architecture, and describe its typical application. At last, we analyze the challenges and future development of space cloud-fog computing.
