In this paper, we consider the Spectrum Sensing (SS) problem in Cognitive Radio (CR). SS
is an important task and one of the main functions of CR, as it has the ability to detect the …

The cognitive wireless sensor network (CWSN) is an important development direction of
wireless sensor networks (WSNs), and spectrum sensing technology is an essential …

Cognitive radio (CR) technology offers a promising solution to the spectrum scarcity problem
via dynamic spectrum access (DSA). Due to the nature of cooperative cognitive radio …

In cognitive radio (CR), the problem of spectrum hole detection has been extensively studied
in single dimension, such as frequency domain, spatial domain, and so on. Recently, a class …

The void spectrum in spread out geographical location and a congestion in spectrum
allotment in different regions of the world has led to the scarcity of precious natural resource …

In Cognitive Radio networks, Secondary Users, or unlicensed users, are able to access the
licensed spectrum in an opportunistic manner. For this reason, Spectrum Sensing can be …

Complex self-organizing cognitive radio (CR) networks serve as a framework for accessing
the spectrum allocation dynamically where the vacant channels can be used by CR nodes …
