Current State and Challenges in Privacy of Software Defined Networks for the Internet of Things

With the help of the IoT, millions of items and gadgets that people use every day may be linked together in a single system. As a result, SDN is fundamental to the development of the IoT. Using a centralized controller designed to manage a wide variety of linked devices, SDN enables programmable and adaptive networking. Intelligent routing, streamlined data gathering, transfer, and analysis, centralized control of network resources and applications, and dynamic, on-demand network reconfiguration are just some of the benefits that may be gained by incorporating SDN into the Internet of Things. Yet, they provide difficulties in areas like as efficiency, compatibility, scalability, dependability, and safety. In this article, we provide a detailed overview of software-defined networking (SDN) for the Internet of Things, including an examination of the interplay between SDN and IoT principles, a look at several SDN-IoT topologies, and a discussion of the associated security and privacy concerns.
