In this article we present a feasibility study of spectrum-sensing techniques using a research
testbed platform for exploration and demonstration of cognitive radio systems. Our cognitive …

Typically, each cooperative spectrum sensing process requires two phases: the primary
user's signal detection phase, in which all cognitive users attempt to detect the presence of …

This paper considers the problem of cooperative spectrum sensing in multiuser multiple-
input multiple-output cognitive radio networks considering the presence of uncertainty in the …

Cognitive radio networks (CRNs) have emerged as an essential technology to enable
dynamic and opportunistic spectrum access which aims to exploit underutilized licensed …

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 …

A major concern in the recent past was the traditional static spectrum allocation which gave
rise to spectrum underutilization and scarcity in wireless networks. In an attempt to solve this …

Spectrum sensing for cognitive radio allows a secondary user to detect spectrum 'holes' and
to opportunistically exploit this space for unlicensed communication. Blind spectrum sensing …

This paper deals with protocol design for cognitive cooperative systems with many
secondary users. In contrast with previous cognitive configurations, the channel model …

Cognitive radio networks (CRNs) are a promising solution to address the spectrum shortage
issue. Spectrum sensing plays a key role to make such a scenario practical. In this letter, we …

This paper proposes a routing algorithm that enhances throughput and decreases end-to-
end delay in industrial cognitive radio sensor networks (ICRSNs) based on ISA100. 11a. In …
