We consider a problem of dynamic spectrum leasing in a spectrum secondary market of
cognitive radio networks where secondary service providers lease spectrum from spectrum …

We consider the problem of spectrum trading with multiple licensed users (ie, primary users)
selling spectrum opportunities to multiple unlicensed users (ie, secondary users). The …

Optimal pricing for dynamic spectrum sharing in" cognitive radio" networks is an open
research issue. In this paper, we address the problem of spectrum pricing in a cognitive …

Spectrum trading is a concept used to describe the economics of dynamic spectrum sharing
in cognitive radio networks. In this paper, we consider the problem of spectrum trading …

We address the problem of spectrum pricing in a cognitive radio network where multiple
primary service providers compete with each other to offer spectrum access opportunities to …

We recently proposed the dynamic spectrum leasing (DSL) paradigm for dynamic spectrum
access in cognitive radio networks. In this paper, we formalize this concept by developing a …

In this paper, we propose the concept of centralized dynamic spectrum leasing (C-DSL), in
which multiple primary users belonging to the same primary system participate in the …

" 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 …

Cognitive radio networks aim at enhancing spectrum utilization by allowing cognitive
devices to opportunistically access vast portions of the spectrum. To reach such ambitious …
