Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

With 5G mobile communication systems having been commercially rolled out, research
discussions on next generation mobile systems, that is, 6G, have started. On the other hand …

This paper proposes a multi-agent deep reinforcement learning-based buffer-aided relay
selection scheme for an intelligent reflecting surface (IRS)-assisted secure cooperative …

This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time …

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 …

In this paper, we investigate secure communication in a two-hop wireless network, where
multiple buffer-aided relays assist to securely forward data from the sender to the destination …

Intelligent reflecting surface (IRS) is deemed a promising technique for future wireless and
mobile technologies due to its ability to reconfigure the radio propagation environment. In …

Ever since the idea of buffers was incorporated in wireless communications, buffer‐aided
relaying has become an emerging breakthrough in the world of transmitting and receiving …
