We consider a cognitive radio network in which a set of base stations make opportunistic
unlicensed spectrum access to transmit data to their subscribers. As the spectrum of interest …

We consider a cognitive radio network in which a set of base stations make opportunistic
spectrum access to support fixed-location wireless subscribers within their cells. The …

A resource allocation framework is presented for spectrum underlay in cognitive wireless
networks. We consider both interference constraints for primary users and quality of service …

We consider a system where a licensed radio spectrum is shared by two networks, namely
the primary network and the secondary network. The spectrum is licensed to the primary …

We consider a cognitive radio network in which a set of base stations make opportunistic
unlicensed spectrum access to transmit data to their subscribers. As the spectrum of interest …

We consider a secondary usage of spectrum scenario where a secondary network coexists
and/or shares the radio spectrum with a primary network to which the spectrum is licensed …

The deployment of cognitive radio networks enables efficient spectrum sharing and
opportunistic spectrum access. It also presents new challenges to the classical problem of …

Spectrum scarcity is the major challenge facing all parties working in the
telecommunications industry. As recently shown, the main problem of spectrum …

We investigate the problem of admission and power control considering a scenario where
licensed, or primary, users and cognitive radios, or secondary users, are transmitting …

We consider QoS-aware spectrum sharing in cognitive wireless networks where secondary
users are allowed to access the spectrum owned by a primary network provider. The …
