The dramatic growth of smart devices catering content-centric data traffic has fueled the
need for group communication services in cellular networks, among which multicasting is of …

Cognitive radio (CR) is an emerging technology that has been around for more than fifteen
years to relieve spectrum shortages. Based on the concept of CR, multiple nodes …

We study the performance of a cognitive small cell network, catering multicast services to
multiple groups of secondary users, using a pre-assigned set of orthogonal channels of …

Cognitive Ad Hoc Radio Networks (CRAHNs) is a technology which has been introduced to
deal with the problem of spectrum depletion. CRAHNs address the spectrum depletion …

Data traffic in the wireless networks has grown at an unprecedented rate. While traditional
wireless networks follow fixed spectrum assignment, spectrum scarcity problem becomes a …

Background and Objective: This communication introduces a multiple secondary user (SU)
cognitive radio (CR) system in a dynamic fading environment, specifically Nakagami-m …

Spectrum scarcity is one of the major challenges facing Mobile Ad Hoc Networks (MANETs).
To address this challenge, a new technology called Cognitive Radio has been introduced …
