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 …

In this paper we discuss a selection of promising and interesting research areas in the
design of protocols and systems for wireless industrial communications. We have selected …

Compounding the confusion is the use of the broad term cognitive radio as a synonym for
dynamic spectrum access. As an initial attempt at unifying the terminology, the taxonomy of …

We investigate the problem of achieving global optimization for distributed channel
selections in cognitive radio networks (CRNs), using game theoretic solutions. To cope with …

Opportunistic spectrum access (OSA) has been regarded as the most promising approach to
solve the paradox between spectrum scarcity and waste. Intelligent decision making is key …

" Cognitive radio" is an emerging technique to improve the utilization of radio frequency
spectrum in wireless networks. In this paper, we consider the problem of spectrum sharing …

In this paper, a new spectrum-sharing model called sensing-based spectrum sharing is
proposed for cognitive radio networks. This model consists of two phases: In the first phase …

The problem of opportunistic access of parallel channels occupied by primary users is
considered. Under a continuous-time Markov chain modeling of the channel occupancy by …

Cognitive radio is an emerging technology that aims for efficient spectrum usage by allowing
unlicensed (secondary) users to access licensed frequency bands under the condition of …

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 …
