Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

The pervasiveness of wireless technology has indeed created massive opportunity to
integrate almost everything into the Internet fabric. This can be seen with the advent of …

Today's wireless networks are characterized by a fixed spectrum assignment policy.
However, a large portion of the assigned spectrum is used sporadically and geographical …

Compounding the confusion is the use of the broad term cognitive radio as a synonym for
dynamic spectrum access. As an initial attempt at unifying the terminology, the taxonomy of …

We propose decentralized cognitive MAC protocols that allow secondary users to
independently search for spectrum opportunities without a central coordinator or a dedicated …

Are you involved in designing the next generation of wireless networks? With spectrum
becoming an ever scarcer resource, it is critical that new systems utilize all available …

It is widely believed that the advances of networking technologies will reshape the future of
telecommunication system. The continuous growth in data traffic originated by mobile users …

Dynamic spectrum policies combined with software defined radio are powerful means to
improve the overall spectral efficiency allowing the development of new wireless services …

In cognitive radio (CR) networks, there are scenarios where the secondary (lower priority)
users intend to communicate with each other by opportunistically utilizing the transmit …

The collaboration of nodes in cognitive wireless networks is a large challenge. This paper
studies the collaborative multi-hop routing in cognitive networks. We propose a new …
