Fault Control Using Triple Modular Redundancy (TMR)

Operating Systems have been widely expanding in terms of capabilities and resources. One of the many unavoidable concerns is the occurrence of a fault in the system. A fault is a violation of the existing system. A fault leads to a single or multiple failure in the system. In order to avoid this type of failure, we need to remove or control the fault. The commonly used techniques for controlling and isolating faults in the system are replication and check pointing. This paper aims to provide control over the detected fault by using the antique technique of triple modular redundancy (TMR) which is a type of N-modular redundancy techniques. Although it has the highest form of reliability, it has not been used to create a fault tolerant system. In our paper, we propose a system using the technique of triple modular redundancy to effectively mask and mitigate the detected faults to provide uninterrupted usage of the entire operating system.
