This paper studies the dilemma between fault tolerance and energy efficiency in frame-based real-time systems. Given a set of K tasks to be executed on a system that supports L voltage levels, the proposed heuristic-based scheduling technique minimizes the energy consumption of tasks execution when faults are absent, and preserves feasibility under the worst case of fault occurrences. The proposed...
In this paper we present an approach to the scheduling and voltage scaling of low-power fault-tolerant hard real-time applications mapped on distributed heterogeneous embedded systems. Processes and messages are statically scheduled, and we use process re-execution for recovering from multiple transient faults. Addressing simultaneously energy and reliability is especially challenging because lowering...
