Fault tolerance is an approach for getting desirable services in the presence of fault. A fault tolerance technique can be static and dynamic depending upon occurrence of fault in a system. A system can be failed if the fault is not tolerated on time. The complexities of systems are increasing day by day which results increasing failure rate in the real time systems. In this paper, a dynamic fault...
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...
The aim is to achieve schedulability of tasks in a real time system with fault tolerance and energy minimization. The fault tolerance can be achieved by maintaining enough time redundancy so that task can be re-executed in presence of fault. During re-execution, check pointing policy gives reliability in a system. First, calculate an optimal number of checkpoints to reduce the redundancy and save...
A fault in a real time system can cause a system 1 failure if it is not detected and tolerated in time. Fault tolerance is an approach used to allow a system to continue the work properly in the presence of fault. Time is an important aspect in real time system to perform an operation. Fault tolerance can be achieved by checkpointing approach to tolerate transient fault. But the issue is how many...
Fault tolerance is an important aspect in real-time applications. It is the technique used to achieve the required results in the presence of fault. Fault tolerance can be achieved by checkpointing approach for transient fault. But the issue is how many checkpoints should be applied with minimum energy consumption. Fault tolerance and energy efficiency is one of the big issues in real time systems...
