Cognitive radio in the context of internet of things using a novel future internet architecture called NovaGenesis

- For the first time, we present a convergence among cognitive radio network (CRN), IoT and a future Internet architecture proposal.
- We present the concept of a low-cost embedded cooperative sensing and cognitive radio architecture for IoT applications.
- We have experimentally demonstrated that the use of cooperative spectrum sensing based on energy detection has overcome the problem known as hidden node.
- The proposed radio approach has been integrated to a future Internet proposal called NovaGenesis, which has been previously developed by our research group.
- We demonstrated novelties on distributed naming resolution for hosts, operating systems, services, and data objects using natural language names and self-verifying names.

Many Internet of Things (IoT) requirements are already at the core of next generation wireless networks, including 5G, cognitive radio and future Internet. There is a huge consilience that the majority of Internet devices will become sensors and actuators equipped over ordinary “things”. As a consequence, the radio environment will increasingly become crowded with thousands of low-cost devices sharing the unlicensed frequency bands. This paper is regarding a convergent solution of future Internet and cognitive radio in the context of IoT. It proposes an embedded and low cost cooperative spectrum sensing solution, which has been experimentally implemented. Furthermore, we present a distributed software-controlled sector aware spectrum sensing architecture to store and analyze the spectrum usage information. Finally, the proposed approach has been integrated to a future Internet architecture called NovaGenesis. A proof-of-concept has been experimentally performed, demonstrating for the first time the convergence of IoT, future Internet and cognitive radio.
