Comparative Study of Conventional and New Approaches for Attaining an Effective Fault Tolerance in IoT

Fault Tolerant IoT devices are the latest products that received more hype from the general public. This sudden hype for fault-tolerant IoT devices is due to some occurrence of faults in the IoT applications which results in the malfunctioning of the entire system. At Present Fault-tolerant IoT devices are expensive, but people prefer them, for better living. In recent years, there has been discussion around the world about the enhancement of fault-tolerant IoT devices as they have become old. The conventional way of attaining fault tolerance is the employment of majority consensus and triple modular redundancy. These techniques are more commonly utilized by people who wish to achieve fault tolerance. As the years passed, the users of fault-tolerant IoT devices desired to upgrade the whole mechanism by adopting fresh techniques. Fault tolerance is achieved by applying a set of analysis and design techniques to create systems with dramatically improved dependability. As new technologies are developed and new applications arise, new fault tolerance approaches are also needed. In the early days of fault-tolerant computing, it was possible to create custom hardware and software solutions from scratch. However, with the current technology, chips contain complex, highly integrated functions, requiring hardware and software to meet various standards in order to be economically feasible. This paper presents a survey and a comparative study on fault tolerance provided in a variety of ways, then suggests an innovative scheme for attaining fault tolerance in IoT.
