To alleviate the spectrum scarcity problem in the licensed cellular networks (LCNs), we
introduce a new paradigm called cognitive multihoming (CM), where a cognitive radio (CR) …

We tackle the challenging problem of streaming multiuser videos over the downlink of a
cellular cognitive radio network (CRN), where each cognitive user (CU) can sense and …

The rapid growing of wireless multimedia applications increases the needs of spectrum
resources, but today's spectrum resources have become more and more scarce and large …

Cognitive Radio (CR) is a new paradigm in wireless communications to enhance utilization
of limited spectrum resources. In this paper, we investigate the resource allocation problem …

We investigate the problem of streaming multi-user videos over the downlink of a cognitive
radio network (CRN), where each cognitive user (CU) can access one channel at a time. We …

Cognitive radio (CR) has been proposed to improve spectral efficiency while avoiding
interference with licensed users. In this paper, we propose a resource allocation (RA) …

In this paper, we develop a cognitive radio (CR)-based architecture for fourth generation
(4G) users that provides real-time delivery of service to its applications through the intelligent …

In this paper, we investigate a joint resource allocation problem based on cognitive radio
(CR) techniques for user equipment with multi-homing capabilities. We consider a …

Cognitive radio has been recently considered as a flexible spectrum usage model to
improve the spectrum efficiency. In this paper, we develop a new power allocation approach …

Most of the existing technologies for cognitive radio network (CRN) is essential for providing
an effective solution for spectrum utilization problem in the wireless medium. Power …
