Abstract
The Internet of Things (IoT) is a novel paradigm that ensures connections between the real and virtual world. Generally, connected things form the real world where components are equipped with wireless interfaces. Accordingly, a huge number of smart devices can interact and communicate directly or through a network infrastructure. As a result, a big amount of data will be generated. However, IoT based networks are not adapted to support data management. Thus, a new architecture design seems to be an efficient solution to deal with the fast growth of data in an IoT environment. In this sens, Software-Defined Networking (SDN) and Network Function Virtualization (NFV) are two techniques which can help to overcome these IoT challenges. The first one enables centralized control of the network. The second one separates the software and hardware of the network function. This paper gives an overview of SDN and NFV based architectures for IoT environments with a focus on challenges and solution.
