Cognitive radio technology has the potential to address the shortage of available radio
spectrum by enabling dynamic spectrum access. Since its introduction, researchers have …

Wireless communications have gained huge attention over the past decades because of
continuously increasing demands. The main goal of all wireless network designers is to …

Energy harvesting (EH) and spectrum harvesting (SH) are two promising and useful green
communication and networking mechanisms for the next-generation wireless networks …

The primary task in cognitive radio is to dynamically explore the radio spectrum and reliably
detect the co-existing licensed primary transmissions across a wide-band spectrum. This …

The problem of spectrum scarcity has surfaced in recent years due to the under-utilization of
spectrum in temporal and spatial domains. To address this issue, various spectrum sensing …

Sensing the wideband spectrum is an important process for next-generation wireless
communication systems. Spectrum sensing primarily aims at detecting unused spectrum …

This work investigates multiband spectrum sensing in a cognitive radio network where a
multi-antenna secondary user attempts to detect several consecutive frequency bands …

During the last decade, Cognitive Radio (CR) has become a popular research topic. The
availability of radio spectrum is in shortage, and CR technology can solve the problem by …

In the field of radio surveillance and cognitive radio, the reception of a signal is usually made
in a non-cooperative manner, which means there exists little prior information to detect the …

(IoT) is an effective step into the smart technology world. Several frameworks are proposed
to build CR and IoT. The phases of the interconnection between IoT and CR is; spectrum …
