Scheduling Algorithms for Cloud Based Cyber-Physical Systems Specification

Abstract

Cyber-physical system (CPS) emphasizes dynamic collaboration of physical process and computation process. Its high demands for real-time, safety, security, and reliability require deep integration of control, computation and communication. To achieve better performance and resource utilization in CPS, we propose a framework named cloud based cyber-physical system (CCPS) which strengthens cooperation among various layers in CPS.CCPS adopts closed-loop control, and makes use of cloud service for data processing in cyber-physical cloud (CPC). In order to balance real-time performance and cost of cloud service, network scheduling algorithms in various cloud models are widely discussed in this paper. In addition, we have a broad discussion on effection of tasks scheduling with respect to stability of controller in CCPS in view of time delay. Accordingly, we give simulation and comparison results of the proposed scheduling algorithms for illustration.
