IoT has revolutionized the modern way of life with the advent of intelligent systems. The traditional network architecture employed in the IoT domain is unable to define sufficient solutions of these challenges for a cost-effective and seamless workflow. The intelligent IoT system ensures scalability in challenging or hostile environments. With the emergence of the SDN domain offering programming ability of the control plane, many of these challenges seemed surmountable. This article presents a synergized overview of the challenges faced by the traditional domain and how they can be overcome by the upcoming domain of SDN-IoT. A thorough analysis of the practical adoptions showcase the feasibility of the solution in a real-time environment. The article examines the state of the art and highlights some of the key open points in the domain, based on shortcomings of the current state of SDN-IoT, that can be taken up for future research.
