This article presents accurate approximation expressions for the outage and secrecy outage
probabilities of relay-assisted free-space optical (FSO) communication links utilizing …

In this paper, we numerically study the secrecy performance of the free-space optical (FSO)
system by considering different eavesdropping scenarios. More precisely, we considered …

Multihop relaying is a potential technique to mitigate channel impairments in optical wireless
communications (OWC). In this paper, multiple fixed-gain amplify-and-forward (AF) relays …

This work is concerned with the physical layer security of the free space optical (FSO)
communication network comprising of a transmitter, a receiver, an eavesdropper (Eve), and …

Security and privacy are two main dominant features of any communication system. In this
paper, physical layer security of free space optical communication system using chaotic …

While the millimeter-wave (mmWave) communication is less susceptible against the
conventional wiretapping attack due to its short transmission range and directivity, this paper …

This paper presents research on the physical layer security performance of a multi-user
mixed RF/FSO system based on optimal user interference. In this system model, the RF link …

In this paper, the physical layer security (PLS) analysis for a decode-and-forward (DF)
protocol based multi-hop hybrid radio frequency (RF)/free space optics (FSO) is presented …

The security-reliability tradeoff (SRT) in free-space optical (FSO) communications is the most
critical property to highlight, especially with respect to the development of wireless optical …
