Evaluation of Two Mixed-Criticality Scheduling Algorithm for Periodic Tasks

Article Preview

Abstract:

Nowadays, there are two approach in mixed-criticality scheduling. One is reservations-based approach such as EDF-VD(Earliest Deadline First-Virtual Deadline) and the Other is priority-based scheduling such as OCBP(Own Criticality Based Priority). This paper compared the two mixed-criticality scheduling algorithm from three aspects. The simulation results show that EDF-VD is better than OCBP in completed tasks and the system utilization, but in unmissed deadline ratio the later owns the better.
