Software Defined Network (SDN) Based Internet of Things (IoT): A Road Ahead

Internet of Things (IoT) and Software Defined Network (SDN) are two emerging technologies. The IoT aims to connect objects over the Internet and the SDN provides orchestration for network management by decoupling the control plane and the data plane. The number of connected objects is in billions, and its management and control is a complex task for a large distributed network. The SDN provides flexibility and programmability in the IoT network without troubling underlying architecture of existing implementations. In this paper, we study different IoT application and domains, and the generalized IoT-SDN solutions over the period of 2012-2016. Furthermore, this paper provides a critical view of the IoT and the SDN technologies, current trends in research and the futuristic contributing factors. A comparative analysis of the existing solutions of SDN-based IoT implementations provides an easy and concise view of the emerging trends.
