Deploying Next Generation IoT Applications Through SDN-Enabled Fog Infrastructures

The next generation of Internet of Things (IoT) applications automates critical, real-world processes from domains such as industry or healthcare. These applications have very strict Quality of Service (QoS) requirements. To meet these requirements, in recent years, the deployment of the application services can be performed not only in the cloud, but also through the fog to enhance the QoS, as well as for the use of programmable, Software-Defined Networks to optimize the QoS of their communications. However, the application and the network dimensions have been addressed separately, which leads to sub-optimal QoS in these critical applications. In this paper, we present the proposal of a framework to optimize the deployment of next-gen IoT applications through the fog that optimizes both, application and network, in a single effort.
