Although intelligent reflecting surface (IRS) can reconfigure the propagation environment to
enhance the performance of both non-orthogonal multiple access (NOMA) and …

In this paper, we evaluate the secrecy performance in terms of secrecy outage probability
(SOP) for Internet of things (IoT) enabled multi-relaying non-orthogonal multiple access …

In this work, multiple energy‐limited Internet of Things (IoT) users are intended to
communicate with their destination (D u D_u). The scheduled IoT user harvests the energy …

Active intelligent reflecting surface (IRS) has attracted great attention due to the
characteristic of changing the propagation channels by amplifying the amplitude and …

Non-orthogonal multiple access (NOMA) is considered to be one of the best candidates for
future networks due to its ability to serve multiple users using the same resource block …

We investigate the secrecy transmission of uplink non-orthogonal multiple access (NOMA)
with the aid of energy harvesting (EH) jammers. During each time frame, communication is …

In this paper, we investigate the physical-layer security for an Internet of Things (IoT)
relaying network employing non-orthogonal multiple access (NOMA) in the context of non …

Combination of unmanned aerial vehicle (UAV) and non-orthogonal multiple access
(NOMA) is deemed as an promising solution to achieving massive connectivity in future …

Non-orthogonal multiple access (NOMA) has been deemed a promising technology to
