Internet of Things (IoT) is considered to be the Internet of the future. Thus, a lot of effort is being invested in finding the best design for a global IoT architecture. Recently, Software-Defined Networking (SDN) surfaced as a new networking paradigm that aims to centralize the network control and to separate the control and the data planes. Thus, one can benefit from SDN to abstract the major management complexities residing in this ubiquitous network of networks. Therefore, dealing with the huge amount of generated data in such network will be a major challenge; so, adopting advanced data technologies (cloud and fog computing) will be essential for the new architecture. In this paper, we review work done concerning the application of SDN to the IoT. Also, we propose and analyze a new SDN-based IoT architecture characterized by the centralization of the network control and the decentralization of the data management.
