Stack-Based Dynamic Resource Access Control Protocol for Real-Time Systems

Scheduling of tasks with resource sharing and hard deadline in Real-Time Software Systems (RTSS) has been an important area of research. The Stack-Based Dynamic Resource access control Protocol (SDRP) is a new protocol that reduces the time complexity of the existing Stack-Based Resource Sharing Protocol (SRP) as well as prevents missing of deadline of a higher priority task having no resource requirement. The SDRP is simple, arguably much easier to understand and more efficient to implement compared to the SRP. A simulator is developed to validate the proposed protocol.
