In this paper, a Stackelberg game is built to model the joint power allocation of the primary
user (PU) network and the secondary user (SU) network hierarchically in orthogonal …

Spectrum sharing is an essential enabling functionality to allow the coexistence between
primary user (PU) and cognitive users (CUs) in the same frequency band. In this paper, we …

Introducing orthogonal frequency division multiplexing (OFDM) into cognitive radio (CR) can
potentially increase the spectrum efficiency, but it also leads to further challenges for the …

We consider OFDMA-based cognitive radio (CR) networks where multiple secondary users
(SUs) compete for the available sub-bands in the spectrum of multiple primary users (PUs) …

Conflict-free power allocation for secondary users (SUs) in cognitive networks is a
challenging problem because the accessible spectrum of the SUs is shared with the primary …

With the promise of improving the spectrum utilization of wireless devices, cognitive radio
technology has gained a significant amount of interest from the research community …

We develop a game theoretic framework for distributed resource allocation in the uplink of a
cognitive radio network where secondary users (SUs) share the bandwidth with primary …

In the present paper, a game theoretic framework of joint channel selection and power
allocation for spectrum sharing in distributed cognitive radio networks is proposed. The …

In this paper, we propose a clustering-based resource allocation (RA) scheme for the
multiuser orthogonal frequency division multiplexing (OFDM)-based cognitive radio network …

The resource allocation problem for orthogonal frequency-division multiple-access (OFDMA)-
based multicast cognitive radio networks is investigated under the spectral activities of …
