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.
