Cognitive Radio Communications and Networks gives comprehensive and balanced
coverage of the principles of cognitive radio communications, cognitive networks, and …

Spectrum is a critical yet scarce resource and it has been shown that dynamic spectrum
access can significantly improve spectrum utilization. To achieve this, it is important to …

Secondary spectrum access is emerging as a promising approach for mitigating the
spectrum scarcity in wireless networks. Coordinated spectrum access for secondary users …

The paradigm of shared spectrum that allows spectrum bands that are underutilized by
primary owners to be exploited opportunistically by secondary devices has been a subject of …

Wireless spectrum is a scare resource, but in practice much of it is underused by current
owners. To enable better use of this spectrum, we propose an auction approach that …

Dynamic spectrum redistribution---under which spectrum owners lease out under-utilized
spectrum to users for financial gain---is an effective way to improve spectrum utilization …

Most spectrum distribution proposals today develop their allocation algorithms that use
conflict graphs to capture interference relationships. The use of conflict graphs, however, is …

The paradigm of shared spectrum allows secondary devices to opportunistically access
spectrum bands underutilized by primary owners. Recently, the FCC has targeted the …

In this paper, we present a game theoretical framework for DSA (Dynamic Spectrum Access)
in cellular networks. We model and analyze the interaction between cellular operators with …

Mobile applications and social networks tend to enhance the needs for high‐quality content
access. To address the expeditious growing demand for data services in 5G cellular …
