Prospect of Improving Internet of Things by Incorporating Software-Defined Network

Internet of Things (IoT) is gaining a significant amount of importance in the field of networking. It uses low-cost devices to provide the application to the users. IoT devices are resource-constraint device, so they suffer from the constraints of availability, reliability, flexibility, and security. Lots of research attention has been given to minimize these challenges. By integrating the features of Software-Defined Network (SDN), most of the IoT issues can be overcome. This paper presents a detail investigation of IoT issues which can be improved by incorporating SDN. The resources used for SDN are equipped with huge computational power. This particular feature can help IoT devices to overcome the constraint problem. The virtualization concept of SDN will help to resolve the scalability issues of IoT. Similarly, many other issues can be resolved at a very low cost. Researchers are finding that SDN-based IoT is much powerful than that of the exiting IoT system.
