An increasing number of vehicles make spectrum resources face serious challenges in
vehicular cognitive small‐cell networks. The means of spectrum sharing can greatly alleviate …

In this paper, a supermodular game theoretic approach is investigated for spectrum sharing
in cognitive radio networks. We consider a Bertrand competition model, in which primary …

In this paper, with the aims of alleviating the pressure from the shortage of spectrum
resource and addressing the inefficient spectrum utilization, we investigate the spectrum …

Cognitive radio is wireless communication system used for higher spectrum utilization for
spectrum holes that are shared between primary (or licensed) users and secondary (or …

Cognitive radio (CR) networks employing dynamic spectrum access have been proposed in
the framework of enabling 5G wireless networks to enhance efficient use of spectrum …

Small cells overlaid with macrocells can increase the capacity of two-tier cellular wireless
networks by offloading traffic from macrocells. To motivate the small cell service providers …

Cognitive radio network is expected to use flexible radio frequency spectrum sharing
techniques to achieve more efficient frequency spectrum usage. This article considers the …

In this paper, we consider the problem of spectrum sharing in a Cognitive Radio Network
(CRN) with spectrum holder, two secondary operators and secondary users (SUs). In the …

The dynamic competition between two bounded rational mobile virtual network operators
(MVNOs) in a duopoly spectrum market is investigated. A two stage game is employed to …

Dynamic spectrum sharing can improve the efficiency of spectrum utilization. Spectrum
trading between primary users (PUs) and secondary users (SUs) is a popular and efficient …
