The integration of cognitive radio and device-to-device (D2D) communication gives rise to
Cognitive D2D (cD2D) communication, which offers numerous advantages, such as …

In this paper, we propose an innovative self‐organizing medium access control mechanism
for a distributed cognitive radio network (CRN) in which utilization is maximized by …

The primary goal of a Cognitive Radio (CR) is to reprocess the spectrum holes and enhance
the limited accessibility of radio spectrum capability. A longer sensing period enhances the …

The detection and characterisation of electromagnetic signals within a specific frequency
range, known as spectrum sensing, plays a crucial role in Cognitive Radio Networks …

In a cognitive radio ad hoc network (CRAHN), the secondary user node has a restricted
range for sensing other users within the network. To enhance the performance of nodes …

Cognitive radio networks (CRNs) have been introduced as a promising solution to optimize
the use of available radio-frequency spectrum. The key idea in CRNs is the proper selection …

With the widespread use of unmanned aerial vehicles (UAVs), spectrum resources are
becoming less and less available. Better utilization of the spectrum can be achieved by …
