With the advent of 5G and the need for energy-efficient massively connected wireless
networks, in this work, we consider an energy harvesting (EH) based multi-relay downlink …

In this paper, we explore the possibilities and advantages of cooperative relaying with the
addition of non-orthogonal multiple access (NOMA). First, the possibilities of NOMA for fifth …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …

Non-orthogonal multiple access (NOMA)-based cognitive radio (CR) networks have recently
emerged as a promising solution to enhance the spectral efficiency and massive …

This paper investigates outage and throughput performance of non-orthogonal multiple
access (NOMA) based underlay cognitive radio (ie, CR-NOMA) network under partial relay …

Capitalizing on the benefits of non-orthogonal multiple access (NOMA) and full-duplex
relaying as key technologies to boost spectral efficiency in the next generation of wireless …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same frequency band to improve the spectral efficiency. Whereas a security flaw emerges in …

Internet-of-Things (IoT) technology has received much attention due to its great potential to
interconnect billions of devices in a broad range of applications. IoT networks can provide …

This paper studies a two-user cooperative non-orthogonal multiple access network with a
novel cooperation scheme, where the source communicates with the near user directly or …

This article investigates the outage performance of a novel two-user multi-relay non-
orthogonal multiple access (NOMA)-based hybrid satellite-terrestrial relay network (HSTRN) …
