Cognitive radio (CR) can successfully deal with the growing demand and scarcity of the
wireless spectrum. To exploit limited spectrum efficiently, CR technology allows unlicensed …

The explosive growth of wireless devices motivates the development of the internet-of-things
(IoT), which is capable of interconnecting massive and diverse" things" via wireless …

Cognitive radio has been widely considered as one of the prominent solutions to tackle the
spectrum scarcity. While the majority of existing research has focused on single-band …

Green communications is an inevitable trend for future communication network design,
especially for a cognitive radio network. Power allocation strategies are of crucial …

Cognitive radio has attracted an increasing amount of interest over the past few years as an
effective method of alleviating the spectrum scarcity problem in wireless communications …

In this paper, we consider power allocation in multiband cognitive radio (CR) networks,
where multiple secondary users (SUs) transmit via a common relay and compete for the …

Spectrum sharing has attracted a lot of attention in cognitive radio recently as an effective
method of alleviating the spectrum scarcity problem by allowing unlicensed users to coexist …

The internet of everything (IoEs) has become a well-known tool for transforming the concept
of connected environments into reality in near future. The cognitive radio network is a …

Fairness among different users and energy utilization are key issues in the future
communication network design. Robust max-min fairness resource allocation in sensing …

Cognitive radio networks (CRNs) have been proposed to exploit licensed bands
opportunistically, with secondary users'(SU) activity being subordinated to primary users …
