Abstract
Fog networking, an emerging concept in the context of cloud computing, is an idea to bring computation, communication and storage near to edge devices. Fog computing can offer low latency, geographically distributed mobile applications, and distributed control systems. On the other side, Software defined networking is a concept to make networking flexible and programmable. These two technologies together can create flexible and scalable networks to handle heterogeneous and massively increasing applications of IoT. In this paper we discuss how these two technologies can interplay with each other to be enabler of next generation IoT. We discuss that why these technologies are important for IoT and what current architectures are available to support IoT.
