Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

Cognitive radio (CR) has emerged as a promising technology to exploit the unused portions
of spectrum in an opportunistic manner. The fixed spectrum allocation of governmental …

A cognitive radio (CR) network refers to a secondary network operating in a frequency band
originally licensed/allocated to a primary network consisting of one or multiple primary users …

Distributed power control is investigated for cognitive radio networks (CRNs) based on a
cooperative game-theoretic framework. Taking into consideration both network efficiency …

We consider a point-to-multipoint cognitive radio network that shares a set of channels with
a primary network. Within the cognitive radio network, a base station controls and supports a …

Cognitive radio networks (CRNs) have emerged as an essential technology to enable
dynamic and opportunistic spectrum access which aims to exploit underutilized licensed …

The cognitive radio (CR) paradigm calls for open spectrum access according to a
predetermined etiquette. Under this paradigm, CR nodes access the spectrum …

Resource allocation (RA) has always had a prominent place in wireless communications
research due to its significance for network throughput maximization, and its inherent …

Opportunistic spectrum access (OSA) in cognitive radio (CR) networks significantly improves
spectrum efficiency by allowing secondary usage of licensed spectrum. In this paper, we …

For about the past decade and a half research efforts into cognitive radio networks (CRNs)
have increased dramatically. This is because CRN is recognized as a technology that has …
