Real-Time Scheduling in Cyber-Physical Systems

Yanwen Chen, Yixiang Chen

Abstract


Cyber-Physical System is a new frontier appearing with many challenges. Real-time issue is an important one in those challenges. To address the problem, in this paper, real-time scheduling algorithms tailored for CPSs are proposed. They are designed for the purpose of maximizing system utilization, reducing scheduling overhead and decreasing context switch cost. Simulation results demonstrate that the strategy of splitting task can improve the system utilization. However, after the system utilization surpasses 75%, the success ratio will reduce because large numbers of splitting tasks have an adverse impact on it.
