Verification of concurrent client-server real-time scheduling systems

Formally verifying complex real time systems is a formidable task due to state-space explosions. We propose a formal framework in which not only is system concurrency modeled, but scheduling policies are also taken into consideration for verifying temporal properties. We show how the verification of concurrent real time systems, modeled as client-server systems, using the model checking approach can benefit from taking advantage of scheduling policies. Integration of these two concepts, namely scheduling and model checking, provides a reduction of the state space when compared to pure model checking strategies. Our implementation and experiments corroborate the feasibility of our approach. Wide applicability, significant state-space reduction, and several scheduling semantics are important features of the framework
