IoT networks are being used these days for several purposed and in many domains.IoT Networks contain several layers of networking and each network is built with small to big things.IoT networks are fragile and therefore tend to fail several times defeating the very purpose of building the IoT networks.The networking layers of the IoT network include device layer, controller layer, services layer, gateway layer, networking layer and the storage layer.Most of the computing within the IoT network is undertaken in services layer.With a single server used at this layer, the fault tolerance of the IoT networks is insignificant.Use of clustered servers enhances the fault tolerance of the IoT network.In this paper, it is shown, how the fault tolerance of the IoT networks improves with use of Butterfly network implemented in the services layer using 4 Servers to process 4 Significant inputs and 4 Significant outputs.The fault tolerance of the IoT network is computed using the FTA model and a probability model that can be used for computing fault tolerance with the services layer when Butterfly network is used for building the IoT network.A Hybrid model of computing the Fault tolerance of the IoT network is presented when services layer is built through a Butter fly model..
