Scheduling real-time of the synchronous hybrid tasks under energy constraint

In this paper, we are interested by the integration of precedence and resources sharing constraints in the real time scheduling of periodic and aperiodic tasks. We also treat the problem of dynamic voltage scaling of the processor in the same context. Many dynamic voltage scaling algorithms have been proposed in the literature. However, these algorithms do not consider the constraints of precedence and shared resources on the scheduling of periodic and aperiodic tasks. In this case, we propose two algorithms with the constraints cited above. Experimental results show that the proposed algorithms reduce the energy consumption under earliest deadline first scheduling policy and the stack resource policy.
