For conventional wireless networks, the main target of resource allocation (RA) is to
efficiently utilize the available resources. Generally, there are no changes in the available …

Cognitive radio (CR) has emerged as a promising technology to exploit the unused portions
of spectrum in an opportunistic manner. The fixed spectrum allocation of governmental …

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 …

Cognitive radio networks will provide high bandwidth to mobile users via heterogeneous
wireless architectures and dynamic spectrum access techniques. However, CR networks …

Cognitive radio (CR) technology is envisaged to solve the problems in wireless networks
resulting from the limited available spectrum and the inefficiency in the spectrum usage by …

This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

Distributed spectrum sensing (DSS) enables a Cognitive Radio (CR) network to reliably
detect licensed users and avoid causing interference to licensed communications. The data …

Opportunistic spectrum access (OSA) has been regarded as the most promising approach to
solve the paradox between spectrum scarcity and waste. Intelligent decision making is key …

Device coordination in open spectrum systems is a challenging problem, particularly since
users experience varying spectrum availability over time and location. We propose a …

In this paper, we present an adaptive and dis-tributed approach to spectrum allocation in
mobile ad-hoc networks. We propose a local bargaining approach where users affected by …
