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

Visible light communication (VLC) has become a promising technology for high data rate
communications and an attractive complementary to conventional radio frequency (RF) …

This paper studies a multi-tier cache-aided relaying network, where the destination is
randomly located in the network and it requests files from the source through the help of …

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 …

Owing to its distinctive merits, non-orthogonal multiple access (NOMA) techniques have
been utilized in unmanned aerial vehicle (UAV) enabled wireless base stations to provide …

Nonorthogonal multiple access (NOMA) assisted semi-grant-free transmission admits grant-
free users to access the channels otherwise solely occupied by grant-based users, and has …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

Future wireless networks have requirements of large connections, low power consumption,
high reliability, and strong security. Considering the abundant available bandwidth of …

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 …

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 …
