Approaches for Transient Fault Tolerance in Multiprocessor - A State of Art

Objectives: This aim of this paper is to analyse different approaches for transient fault tolerance like PBS, RM-FT, FSP, BCE and MWFD. Methods: Transient faults are emerging as a critical issue in the reliability of real time systems. Besides multiprocessors being an apparent part of various booming technologies now-a-days, it becomes evident to make these systems susceptible, reliable and consistent to transient faults. Thus, to address the increasing susceptibility of multiprocessors systems to transient faults, different approaches are analysed to counter transient faults. Findings: To identify the optimal method for various constraints like slack time, reduction in time space and reconfiguration etc. Applications: This comparative analysis will help for us to identify the optimal approaches for tolerating the transient fault in critical real time systems.
