Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

In this survey paper, we characterize the learning problem in cognitive radios (CRs) and
state the importance of artificial intelligence in achieving real cognitive communications …

Wireless networks with their ubiquitous applications have become an indispensable part of
our daily lives. Wireless networks demand more and more spectral resources to support the …

Cognitive radio (CR) is regarded as an emerging technology, which equips wireless devices
with the capability to adapt their operating parameters on the fly based on the radio …

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 …

Abstract The US Federal Communications Commission (FCC) defines white space as the
channels that are unused at a specific location or time. For futuristic cognitive radio (CR) …

Designing an efficient spectrum assignment (SA) mechanism is a key issue for realizing
dynamic spectrum access in cognitive radio network. In multi-channel selection based SA …

Wireless communications have gained huge attention over the past decades because of
continuously increasing demands. The main goal of all wireless network designers is to …

We examine the impact of limited channel knowledge on the secondary user (SU) in a
cognitive radio system. Under a minimum signal-to-interference noise ratio (SINR) constraint …

A mobile ad hoc network (MANET) poses significant challenges such as route failure and
end-to-end delay due to the decentralized nature of mobile ad hoc wireless networks …
