Spectrum Management in IoT
In order to underpin the predicted growth of the Internet of Things, a highly scalable, reliable and available connectivity technology will be required. Whilst numerous technologies are available today, the industry trend suggests that cellular systems will play a central role in ensuring IoT connectivity globally. However, since the turn of the century, the cellular industry has been experiencing a tremendous growth in mobile data traffic. Challenged by this unprecedented data surge, researchers and network operators have proposed and implemented new protocols, transmission technologies, and network infrastructure solutions aiming at making the cellular technology as an efficient infrastructure for IoT. To this end, our focus in this area of research is to optimize the spectrum management in order to accommodate the requirement of the internet of things. Indeed, spectrum management represents one of the main challenges that we need to optimize for the future of IoT. Indeed, wireless communication systems are continuously evolving and growing, leading to an increasing need for spectrum resources. Although different spectrum bands are allocated to specific services, it was identified that these bands are unoccupied most of the time or partially used by the primary users. Thus, we need to do something in order to optimize the usage of this scarce spectrum resource. Cognitive radio (CR) was proposed as one of these solutions enhancing the spectrum usage efficiency.
