As a kind of intelligent communication technology, the characteristic of dynamic spectrum
allocation of cognitive radio provides feasible scheme for sharing with the spectrum …

Spectrum trading benefits primary users (PUs) by monetary gains and secondary users
(SUs) by spectrum accessing opportunities in cognitive radio networks (CRNs) …

Cognitive radio is a promising paradigm to achieve efficient utilization of spectrum resource
by allowing the unlicensed users to access the licensed spectrum. Designing mechanism …

In this paper, we propose an evolution game based spectrum allocation algorithm for
cognitive radio networks, where primary users lease their spare spectrum to secondary …

We consider a dynamic spectrum access scenario in which transmission opportunities are
allocated to users based on a second price, sealed bid auction. Each user experiences a …

Distribute antenna system (DAS) can provide high date rate transmission to satisfy the
service requirements for the rapid growing wireless applications. Besides, the increasing …

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

In this work, we address competition among autonomous cognitive radios (CRs) which are
competing for frequency bands, and model their interactions. We design auction …

In cognitive radio networks (CRNs), spectrum trading is an efficient way for secondary users
(SUs) to achieve dynamic spectrum access and to bring economic benefits for the primary …
