An Approach to Compute Fault Tolerance of an IoT Network having Clustered Devices Using Cross bar Networks

Abstract

Enhancing the fault tolerance of IoT networks is a challenging task as the network is achieved using small and fragile things, local and remote thing, less computing to heavy computing. IoT Networks contain several layers and each layer is built with different clustered and Un-clustered things. In each layer different architecture is followed making it difficult to computing fault tolerance of the network especially when clustered architectures are used. FTA (Fault Tolerance Analysis) is one Technique normally used for computing fault tolerance of an IoT network. This technique becomes complicated when a different type of Topologies are used for connecting things in different Layers of a network. In this paper a Hybrid Methodology is presented to compute fault tolerance of an IOT network when clustered devices are connected in a Cross bar network within the device Layer.
