Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

Relays receive and retransmit signals between one or more sources and one or more
destinations. Cooperative relaying is a novel technique for wireless communications that …

This paper investigates the impact of relay selection (RS) on the performance of cooperative
non-orthogonal multiple access (NOMA), where relays are capable of working in either full …

Hybrid radio frequency (RF)/free space optical (FSO) systems are among the candidate
enabling technologies for the next generation of wireless networks, since they benefit from …

In this article, relay-assisted computation offloading (RACO) is investigated, where user A
wishes to share the results of computational tasks with another user B with the assistance of …

In this paper, we investigate the fading two-hop full-duplex (FD) relay channel with self-
interference, which is comprised of a source, an FD relay impaired by self-interference, and …

This is the second part of a two-part paper considering bidirectional relay networks with half-
duplex nodes and block fading where the nodes transmit with a fixed transmission rate. In …

In this paper, we consider a wireless powered cooperative non-orthogonal multiple access
(NOMA) relay network, in which one source is supposed to send independent messages to …

We investigate adaptive transmission schemes over a hybrid radio frequency (RF)/free
space optical (FSO) backhaul network for connecting macro-cell base station with small-cell …

In this paper, we consider the problem of relay-assisted free space optical (FSO)
communications in the case where the relays are equipped with buffers of finite size. The …
