Development of Scheduler for Real Time and Embedded System Domain

We discuss scheduling techniques to be used for real-time, embedded systems. Though there are several scheduling policies, the preemptive scheduling policy holds promising results. In this research paper, the different approaches to design of a scheduler for real-time Linux kernel are discussed in detail. The comparison of different preemptive scheduling algorithms is performed. Hence, by extracting the positive characteristics of each of these preemptive scheduling policies, a new hierarchical scheduling policy is developed. The proposed hierarchical scheduling for real time and embedded system will be implemented for a prototype system, using C or C++ language. It is expected that the new scheduling algorithm will give better performance with respect to satisfy the needs, such as time, capturing and usage of resources of different applications.
