In this paper, we investigate covert communications in data collected IoT with NOMA, where
the paired sensor nodes S m and S n transmit covert messages to a legitimate receiver …

The combination of simultaneously transmitting and reflecting-reconfigurable intelligent
surface (STAR-RIS) and nonorthogonal multiple access (NOMA) brings the necessary full …

With the gradual promotion of the fifth generation (5G) mobile communication and Internet of
Things (IoT) applications, wireless communication transmission will be more vulnerable to …

This letter proposes a joint covert and secure transmission scheme in the non-orthogonal
multiple access (NOMA) networks against internal eavesdropping and external monitoring …

In this letter, we investigate the covert communication in uplink non-orthogonal multiple
access (NOMA) system against a warden who can also execute successive interference …

It is challenging to covert communication under channel distribution information (CDI)
uncertainty caused by limited feedback and rapid-changing channels. This letter …

Mobile edge computing (MEC) is a key enabling technology for the sixth-generation (6G)
wireless networks. In this paper, we apply covert communications to MEC to prevent …

Abstract As the Internet of Things (IoT) becomes increasingly popular, the amount of
information transmitted through the IoT network has increased significantly. Therefore, the …

In this paper, we investigate covert communication in an intelligent reflecting surface (IRS)-
assisted non-orthogonal multiple access (NOMA) system, where a legitimate transmitter …

This paper investigates covert communication in simultaneously transmitting and reflecting
