Abstract

Recently, there has been an increasing interest in the Internet of Things (IoT). While some analysts disvalue the IoT hype, several technology leaders, governments, and researchers are putting serious efforts to develop solutions enabling wide IoT deployment. Thus, the huge amount of generated data, the high network scale, the security and privacy concerns, the new requirements in terms of QoS, and the heterogeneity in this ubiquitous network of networks make its implementation a very challenging task. SDN, a new networking paradigm, has revealed its usefulness in reducing the management complexities in today’s networks. Additionally, SDN, having a global view of the network, has presented effective security solutions. On the other hand, fog computing, a new data service platform, consists of pushing the data to the network edge reducing the cost (in terms of bandwidth consumption and high latency) of “big data” transportation through the core network. In this paper, we critically review the SDN and fog computingbased solutions to overcome the IoT main challenges, highlighting their advantages, and exposing their weaknesses. Thus, we make recommendations at the end of this paper for the upcoming research work.

CONCLUSION

The network and telecommunication networks are in continuous evolution. Internet of Things is expected to take advantage of this evolution to be widely deployed. While some IoT applications are already there, its wide realization still encumbered by many challenges such as the high scalability and management complexity, the heterogeneity and interoperability support, the big data handling, and the security and privacy guarantee. These main challenges need new architectural and design based solutions to be handled. In this paper, we presented SDN & NFV, cloud and fog computing, and 5G as the main enablers of the IoT evolution. Many architectural solutions have been conceived in the IoT domain, but no one has gained a global acceptance and adoption. We believe that SDN is a solution that combats the heterogeneity and can serve in unifying the vision of a global IoT architecture. While the work in this domain is still in its early stages, we presented the most recent work applying SDN & NFV in an SDN based IoT architecture.
