An efficient checkpointing approach for fault tolerance in time critical systems with energy minimization

Aim of this paper is to find efficient number of checkpoints for transient fault tolerance in time critical systems. Energy is also the constraint in these battery operated systems due to small and fixed battery. A fault in time critical systems may cause damage if not tolerated in time. Time is an important aspect in these systems to perform an operation. A transient fault can be removed by check pointing policy but the goal is to apply efficient number of checkpoints to enhance battery utilization and schedulability. A system must be fault tolerant to work in fault prone environment. The proposed approach is more suitable to tolerate transient fault and enhancing schedulability with minimum energy consumption. The results and simulation shows that our proposed approach is better with respect to energy consumption and efficient checkpoints.
