Energy efficient approach for transient fault recovery in real time systems

Abstract

Due to increase in complexity of systems, failure rate is increasing in real time systems. A failure in a system can occurs due to presence of fault. A fault can be transient, intermittent or permanent. In this paper we propose a novel approach for transient fault recovery with energy minimization. A faulty system may cause a failure. Fault tolerance approach is used to correct functioning in the presence of fault. DVS (Dynamic Voltage Scaling) is responsible for energy minimization in a system by adjusting the voltage level and clock speed dynamically. Efficiency of DVS depends upon available slack time. Experimental result shows that proposed algorithm is more suitable for transient fault recovery with energy minimization.
