ABSTRACT
This paper introduces a novel design approach for real-time multi-resource scheduling aimed at ensuring upper-bounded average response time in interactive computer services. By analyzing the properties of conventional heuristics, this work presents a new algorithm which combines resource and queue disciplines in an orthogonal scheduling architecture which extends recent results on stochastic real-time operations with applications on SOA and pervasive computing environments. Simulation experiments shows how the attributes of the proposed technique can outperform those of conventionally employed alternatives.

Analysis on quantum-based fixed priority scheduling of real-time tasks
ICUIMC '09: Proceedings of the 3rd International Conference on Ubiquitous Information Management and CommunicationFixed priority schedulers are widely used for real-time systems, and there were efforts to improve the schedulability. Preemption threshold scheduling is one of such efforts with a dual priority scheme. It increases the schedulability by introducing ...
