Fault Tolerance Approach with Energy Harvesting in Real Time System

Real time systems are widely used systems in now days. Most of these systems work in fault prone environment. The job running in these systems should be finished on its deadline as timing constraints which requires some energy to finishing it. If there is any fault occurring in the system then it may not be possible that the job running will finish on its deadline and will give the desired result. Fault tolerance is the technique to give the required output in the presence of fault which can be achieved by different methods. Fault tolerance can be achieved by checkpointing to overcome the problem of total reexecution. In this paper we will propose the checkpointing scheme for energy harvesting real time system in which task running in such a way that it will finish on time with minimum energy consumption. The energy is harvesting from different resources which can be managed through dynamic voltage scaling (DVS).
