IoT Based Innovative Dual Level Control System with Fault Tolerance & Fail Safe Capability

IoT provides a machine to machine link capability thus ensuring continuous acquisition of data from sensor, machines, objects connected at any point on the Internet. Normally, used for acquisition of data on the cloud, IoT is gradually moving on to the next phase of evolution wherein control of actuators for automating applications is a point of focus. Control action requires a robust yet flexible mechanism, to ensure that no breakdown in the control action occurs at any point of time despite failure of communication link between the cloud and the objects. This paper provides information about the solution for ensuring continuity of control action despite link failure by implementing a dual level of control mechanism. The simulation results and a limited hardware implementation have been implemented to demonstrate the proof of concept.
