Promises, Challenges and Opportunities of Integrating SDN and Blockchain with IoT Applications: A Survey

Security is a major issue in the IT world, and its aim is to maintain user confidence and the coherence of the entire information system. Various international and European research projects, as well as IT manufacturers, have proposed new solutions and mechanisms to solve the problem of security in the IoT environment. Software-Defined Networking (SDN) and Blockchain are advanced technologies utilized globally for establishing secure network communication and constructing resilient network infrastructures. They serve as a robust and dependable foundation for addressing various challenges, including security, privacy, scalability, and access control. Indeed, SDN and Blockchain technologies have demonstrated their ability to efficiently manage resource utilization and facilitate secure network communication within the Internet of Things (IoT) ecosystem. Nonetheless, there exists a research gap concerning the creation of a comprehensive framework that can fulfill the unique requirements of the IoT environment. Consequently, this paper presents a recent investigation into the integration of SDN and Blockchain with IoT. The objective is to analyze their primary contributions and identify the challenges involved. Subsequently, we offer relevant recommendations to address these challenges and enhance the security and privacy of the IoT landscape.
