Cognitive radio (CR) has been considered as a potential candidate for addressing the
spectrum scarcity problem of future wireless networks. Since its conception, several …

Cognitive radio networks (CRN), in their quest to become the preferred next-generation
wireless communication paradigm, will depend heavily on their ability to efficiently manage …

Envisioning the potentials of energy harvesting technology and the improved spectrum
reuse by joint utilization of overlay and underlay modes, this paper studies the throughput …

In this paper, we consider a hybrid underlay-overlay cognitive radio with energy harvesting.
In the considered system, secondary user can harvest energy from the primary user's signal …

The upcoming Intelligent Transportation System (ITS) supported by sixth generation (6G)
communication technologies is expected to face the great challenges of spectrum scarcity …

In this paper, the hybrid interweave/underlay channel access mode is studied for an energy
harvesting (EH) cognitive radio network with multi-class secondary users (SUs). The hybrid …

In the recent years, wireless applications and services have grown tremendously, resulting
to a shortage of radio spectrum. On one hand, most of the available radio spectrum has …

Cognitive radio networks (CRNs) have been proposed to exploit licensed bands
opportunistically, with secondary users'(SU) activity being subordinated to primary users …

Cognitive radio (CR) is a rising technology that unlocks the doors for radio spectrum scarcity
problem, which is of great concern nowadays among the researchers at various levels. CR …

In order to beneficially exploit the scarce wireless spectral resources, spectrum sharing
between communication and radar systems has become a promising research topic …
