Computing Offloading-based Task Scheduling for Space-based Cloud-fog Networks

With the continuous development of space technology, the traditional single-star single-chain satellite system cannot meet the increasing requirements of computing resources. The space-based cloud network is the main development direction in the future. In this paper, the space-based cloud-fog computing architecture is introduced, in addition, a hierarchical collaboration-based computing offloading (HCCO) scheme and a multi-point collaboration-based computing offloading (MPCO) scheme for space-based cloud-fog network task scheduling are proposed. The simulation results show that the proposed schemes can reduce the job complete time (JCT) and meet the low latency requirement of latency-sensitive services.
