A Fault-Tolerant Scheduling Algorithm for Heterogeneous Distributed Control Systems
Zhu Shao-ping · 2004
The fault-tolerant scheduling algorithm almost demands that all tasks' periods are the same and equal to their deadlines, but in fact the periods are not the same in many cases.But the algorithm are devised for homogeneous distributed systems, which have identical processors and priorities. According to the characteristics of distributed control systems and the technique of primary/backup copies, In this paper we propose a fault-tolerant scheduling algorithm for heterogeneous distributed control systems, the algorithm sorts all the tasks according to their priority in order to improve it's efficiency greatly.
