A Survey on Research Challenges and Applications in Empowering the SDN-Based Internet of Things
Many challenges arise due to the increase in the number and variety of Internet-connected devices. Modern data center has immensely improved and gained momentum in providing cloud computing services for handling heterogeneous application and for satisfying various customer needs. Internet of things (IoT) enables numerous number of devices with network connectivity to communicate, to gather, and exchange information for providing smarter services. Management and performance tuning of billions of devices that are geographically distributed has become a challenging and complex task. To overcome the limitations of traditional networking, Software-Defined Networking (SDN) technologies were developed. SDN offers flexibility, agility, programmability, and addresses end-to-end connectivity issues that are prevalent in managing dynamic traffic patterns and real-time traffic flows. This paper surveys and investigates the SDN principles, research challenges, and presents an insight into SDN-based IoT.
