The Internet of Things (IoT)-centric concepts like augmented reality, high-resolution video
streaming, self-driven cars, smart environment, e-health care, etc. have a ubiquitous …

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 …

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 …

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 …

Abstract The Open Spectrum approach to spectrum access can achieve near-optimal
utilization by allowing devices to sense and utilize available spectrum opportunistically …

Spectrum bands are the backbone of wireless networks. Every user is allocated a fraction of
the spectrum from available fixed spectrum band. But, the fixed available spectrum band …

Congestion in the RF spectrum is rapidly increasing, which has motivated the need for
efficient spectrum sharing techniques. A cognitive radar system has been developed to …

In this paper, we propose a dynamic channel-selection solution for autonomous wireless
users transmitting delay-sensitive multimedia applications over cognitive radio networks …

Channel allocation was extensively studied in the framework of cellular networks. But the
emergence of new system concepts, such as cognitive radio systems, has brought this topic …
