Abstract

The checkpointing problem in real-time systems equipped with on-line fault detection mechanisms is dealt with from a reliability point of view. The reliability analysis is performed with the assumption that transient faults occur in accordance with a Poisson process and are detected immediately by the detection mechanisms. And the best equidistant checkpointing strategy that maximizes the reliability of the system against transient faults is derived.
