This letter investigates covert communication in an intelligent reflecting surface (IRS)-
assisted system. We propose a novel algorithm that jointly optimizes the transmission …

The accuracy of the location estimation of sensors in wireless sensor networks (WSNs) is
important to many applications such as environment surveillance applications. In large-scale …

Covert communications, or covert channels, are commonly exploited to establish a data
exfiltration channel from an insider on a trusted network to a malicious receiver outside the …

It is expected that the sixth-generation (6G) cellular networks will provide high-accuracy
positioning services. For the millimeter wave (mmWave) frequency band in 6G, both the …

In this paper, we propose a privacy-preserving range-based positioning scheme, named
PPRP, which can preserve the location privacy of both user equipment (UE) and anchors …

The anchors in wireless network localization system suffer from the risk of location leakage,
which may result in some catastrophic dangers. To preserve the location privacy of anchors …

High-precision location has become indispensable information in the era of Internet of
Everything. However, the emergence of various location-based services leaves people …

Semantic communication has emerged as a revolutionary paradigm within wireless edge
networks, showcasing remarkable communication efficiency. In contrast to traditional bit …

To realize secure communication and prevent eaves-droppers from detecting the existence
of communication activities, covert communication has attracted substantial research …
