This is a very challenging task, comprising information acquisition, information analysis, decision-making, and action implementation on large scale IoT networks.
Resulting in research to explore the integration of software-defined networking SDN and IoT for a simpler, easier, and strain less network control. SDN is a promising novel paradigm shift which has the capability to enable a simplified and robust programmable wireless network serving an array of physical objects and applications.
This paper starts with the emergence of SDN and then highlights recent significant developments in the wireless and optical domains with the aim of integrating SDN and IoT. Use of this web site signifies your agreement to the terms and conditions. The interconnection devices take forwarding decisions solely based on a set of multi-criteria policy rules defined by external applications called controllers.
It is possible to let multiple controllers manage each element of a given network, which allows to create independent networks on the same physical infrastructure. If the implementation of SDN in wired networks is relatively easy, it poses a lot of radio-specific problems in the wireless domain, related to link isolation or to channel estimation.
Nevertheless, the wireless domain is also where SDN bears the highest potential, as it provides functions that could foster a better collaboration between access points to reduce interferences or to enhance security.
