Energy-harvesting (EH) and wireless power transfer are increasingly becoming a promising
source of power in future wireless networks and have recently attracted a considerable …

In this study, the authors propose a cooperative transmission scheme with energy‐
harvesting (EH) relays under wiretapping of an eavesdropper. In this scheme, the relays …

Unmanned aerial vehicle (UAV) communications have been widely accepted as promising
technologies to support air-to-ground communications in the forthcoming sixth-generation …

We propose transmit antenna selection with receive generalized selection combining in dual-
hop cognitive decode-and-forward relay networks with spectrum sharing for reliability …

In this paper, an energy harvesting architecture in an Underlay Cooperative Cognitive
Network (UCCN) is investigated, in which power constrained Decode-and-Forward relays …

In this paper, we propose physical layer security for cooperative cognitive radio networks
(CCRNs) with relay selection in the presence of multiple primary users and multiple …

Cognitive radio is a promising technique to resolve the growing scarcity of the indispensable
spectrum resources in wireless applications. Among its three major implementation …

The achievable rates of multicell/multiuser massive multiple-input multiple-output (MIMO)
relay networks with underlay spectrum sharing are investigated for imperfect/perfect channel …

This study first modifies the traditional partial relay selection in cooperative cognitive
networks to prevent error propagation and then proposes exact and asymptotic outage …

Energy efficiency has become an encouragement, and more than this, a requisite for the
design of the next-generation wireless communication standards. In this paper, a dual-hop …
