Space-based Cloud-fog Computing Architecture and its Applications

With the development of space technology, it is an inevitable trend to construct a flexible and efficient computing system for space-based information network. The traditional single-satellite computing can't meet the increasing computing requirements, and the single-satellite resource utilization rate is unsatisfactory. This paper proposes a creative space-based cloud-fog computing architecture, which combines the cloud-fog computing technology with the space-based information network. This architecture is expected to change the traditional mode of data processing that relies on ground nodes by introducing the space-based edge cloud and fog satellites. It can also significantly improve the computing and the service capabilities of on-orbit satellites. Using this computing architecture can save the transmission bandwidth of satellite-ground links and improve the real-time performance of time-sensitive service processing, bringing inspirations and innovations to the development of space information networks. In this paper, we also propose some applied scenarios and implement a simulation for verifying this computing architecture.
