Empirical Study on different protocols used in monitoring and controlling applications of Internet of Things

The fast evolution of IoT has led to the introduction of newer networks such as Industrial Internet of Things (IIoT), Internet of Everything (IoE), and Internet of Automation (IoA) etc. Hence the design of protocols and interfaces remains a challenge, in spite of vast technological advancements. This paper addresses Taxonomy of IoT, and different IoT protocols in each layer of IoT protocol stack and their comparisons are discussed, the open issues and the challenges associated with IoT are classified, finally the current research and scope for future direction is analyzed.
