Recent research trends are shifting toward Internet of Things (IoT) networks based on
cognitive radio (CR) technology to provide dynamic spectrum access to numerous IoT …

Cognitive Radio and 5G are two emanating technologies, which empower the wireless data
transmission. The need for more bandwidth and its utility will demand more spectrum …

Objective: Cognitive radio technology allows the opportunistic usage of licensed spectrum
resources by unlicensed users. The most important function of the cognitive radio …

In this paper, we developed a software defined radio (SDR) system for implementing energy
detection spectrum sensing. The SDR module can be used for a wide range of applications …

Spectrum sensing in cognitive radio network determines whether the channel is currently in
use or not by the primary user (PU). If the channel is detected to be free, it may be allocated …
