Federated learning (FL) is an emerging technology for empowering various applications that
generate large amounts of data in intelligent cyber–physical systems (ICPS). Though FL can …

To extend the transmission range governed by limited transmit power, collaborative
beamforming (CB) can be employed with a virtual antenna array (VAA) constructed by an …

This paper considers the downlink of reconfigurable intelligent surface (RIS) assisted
cooperative non-orthogonal multiple access (CNOMA) systems. Our objective is to minimize …

This letter proposes a two-stage reconfigurable intelligent surface (RIS)-assisted
transmission scheme for cooperative non-orthogonal multiple access networks with …

High throughput, secure transmission, and minimum interference are required in beyond-
fifth-generation (B5G) networks. For this purpose, a mix of hybrid non-orthogonal multiple …

Cooperative user relaying (CUR) is emerged as an effective framework for 6G networks to
address and improve the coverage, system capacity, and transference reliability, without the …

We investigate physical layer security of a downlink cooperative non-orthogonal multiple
access system with an untrusted relay. A friendly jammer (FJ) is employed in order to …

This paper investigates the physical layer security of inband underlay Device-to-Device
(D2D) communication, where the direct link between D2D users is not available. In this …

Abstract Cooperative Non‐orthogonal Multiple Access (C‐NOMA) is projected as the
dominant technology for 5G and beyond. Also, physical layer security, due to the presence …

To guarantee secure information transmission within two sources, a full-duplex (FD) relay
jamming scheme for two-way energy harvesting (EH) cooperative networks is proposed, in …
