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 article investigates energy-efficient secure communication design with the help of
multiple phase-adjustable intelligent reflecting surfaces (IRSs). By creating desirable …

This article considers a relay-based underlay cognitive radio vehicular network, where a
secondary source vehicle transmits information to a secondary destination vehicle with a …

In this paper, an intelligent reflecting surface (IRS) assisted wireless secure communication
system is studied. A multi-antenna access point (AP) intends to send confidential information …

Unmanned Aerial Vehicle (UAV) clustering is promising for performing large-scale missions
because of high mobility and easy deployment. However, the connectivity problems caused …

Ensuring the security and reliability of cooperative vehicle-to-vehicle (V2V) communications
is an extremely challenging task due to the dynamic nature of vehicular networks as well as …

In this article, we investigate the physical layer security for a wireless communication system
consisting of a base station (BS) and a user (U) in the face of an eavesdropper (E). A friendly …

This paper evaluates the secrecy performance for the amplify‐and‐forward (AF) protocol
with partial relay selection (PRS) schemes in the scenario of multiple independent but not …

To boost energy saving for the general delay-tolerant IoT networks, a two-stage, and single-
relay queueing communication scheme is investigated. Concretely, a traffic-aware N …

We investigate the performance of a dual-hop inter-vehicular communications (IVC) system
with relay selection strategy. We assume a generalized fading channel model, known as …
