Cognitive radio technology, a revolutionary communication paradigm that can utilize the
existing wireless spectrum resources more efficiently, has been receiving a growing …

This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

A minimal interrupted communication link setup is the primary objective of the MAC layer.
The MAC layer is responsible for accessing the communication channel. At MAC, a control …

Spectrum handoff in cognitive radio networks (CRN) enables the cognitive radio (CR) users
to guarantee the desired QoS of the primary users. The handoff schemes grant an efficient …

Cognitive radio networks are a promising technology for the improvement of the spectrum
utilisation. The basic idea is to maximise the utilisation of the available spectrum by …

In the cognitive radio (CR) networks consisting of selfish users competing for spectrum
resources, the social optimum is usually not achieved at the Nash equilibrium (NE) of the …

In this paper, the pricing and the transmission power control processes are investigated in a
cognitive radio network. In the given network, there are multiple primary service providers …

In the study of power control and allocation based on pricing, the utility of secondary users is
usually studied from the perspective of the signal to noise ratio. The study of secondary user …

Modeling wireless access and spectrum markets is challenging due to a plethora of
technological and economic aspects that affect their performance. This work develops a …

In a cognitive radio network, selfish secondary users may not voluntarily contribute to
desired cooperative sensing. We design the first fully distributed scheme to incentivize …
