The lack of communication between local authorities, first aid responders, and the
population that are present in a natural disaster area, represents critical aspects which can …

Intelligent reflecting surface (IRS) has been deemed as an energy and spectral-efficient
technology, that can potentially enhance network coverage and transmission reliability, with …

In this paper, a dual-hop underlay cognitive relay network (CRN) with a best-relay selection
(BRS) scheme under spectrum-sharing constraints from the primary user (PU) is …

Abstract RF Spectrum Decision in Cognitive Radio enables unlicensed users of wireless
communication systems to occupy the vacant spectrum slotsasasolution to scarce spectrum …

Device-to-device (D2D) communications is a promising approach for wireless
communications in terms of energy and spectrum efficiency. However, such communications …

The limitation of the radio spectrum and the rapid growth of communication applications
make optimal usage of radio resources essential. Cognitive radio (CR) is an attractive …

In this work, a cooperative optical Internet of Underwater Things (IoUT) system with hybrid
