Cognitive radio has been proposed as a promising technology to resolve the spectrum
scarcity problem by dynamically exploiting underutilized spectrum bands. Cognitive radio …

In this letter, we study the cooperative energy-based combination for spectrum sensing in
cognitive radio networks. Linear combination rule is investigated to minimize the probability …

Cooperative spectrum sensing has been studied to combat the hidden terminal problem by
exploiting the spatial diversity in cognitive radio (CR) networks. This paper concerns blind …

Pervasive wireless computing and communication have created an ever-increasing demand
for more radio spectrum. Since, most of the spectrum is underutilized, it motivated the …

Spectrum sensing for cognitive radio allows a secondary user to detect spectrum 'holes' and
to opportunistically exploit this space for unlicensed communication. Blind spectrum sensing …

Spectrum sensing is an important step toward enabling dynamic spectrum access in
cognitive radio networks. To ensure that primary users are properly protected while …

We propose a novel cluster based cooperative spectrum sensing algorithm to save the
wastage of energy, in which clusters are formed using fuzzy c-means (FCM) clustering and a …

Cognitive sensor network (CSN) is a promising paradigm to address the spectrum scarcity
problem in traditional wireless sensor networks. Reliable spectrum sensing is essential to …

Rapidly rising energy costs and increasingly rigid environmental standards have led to an
emerging trend of addressing “energy efficiency” aspect of wireless communication …

Ultra-densification is one of the main features of 5G networks. In an ultra-dense network,
how to conduct interference management and spectrum allocation is a challenging issue …
