As threats in the maritime domain diversify, securing data transmission becomes critical for underwater wireless networks designed surveillance of infrastructure and border protection. This has sparked interest Quantum Key Distribution (QKD). In this paper, we present an FPGA-based real-time implementation QKD system based on BB84 protocol. The unit is built a hybrid computation consisting FPGA on-board computer (OBC) interfaced with optical front-ends. A photon counting module implemented...

Visible light communication (VLC) allows the dual use of light-emitting diodes (LEDs) for illumination and purposes. With its large bandwidth immunity to electromagnetic interference, VLC can be used as complementary and/or alternative radio communications. In this paper, we present a comprehensive experimental evaluation softwaredefined system with on-off keying both line-of-sight (LOS) non-line-of-sight (NLOS) scenarios. The set-up is based on pair modified National Instruments USRPs...
Vehicular connectivity is envisaged to extend vehicle on-board camera videos the nearby vehicles in order increase drivers' road awareness. This paper demonstrates possibilities of video transmission captured by forward-looking via visible light communications (VLC) using taillights provide see-beyond front assistance. Line sight (LoS) inter-vehicular direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based VLC with data rate 6.42 Mbps and lower latency than...
In this paper, we present our custom design atmospheric channel emulator for free space optical (FSO) system evaluations in a controlled environment. Our is the form of an chamber with dimensions 60 cm × 40 300 cm. It equipped adjustable heaters, coolers and fans to create turbulence. also houses fog generator droplet watering generate different weather conditions. Using custom-design emulator, experimentally investigate performance FSO links at wavelengths
Visible light communication (VLC) uses light-emitting diodes (LEDs) to transmit data by turning them on and off at very high speeds, too fast for the human eye perceive. In outdoor environments, LED-based streetlights can be utilized as VLC transmitters. Given ubiquity of street lights, they are particularly useful broadcasting required in public safety systems. this paper, we develop an FPGA-based system with on-off keying using a streetlight. The is built upon Eclypse Z7 FPGA platform...
Vehicular communication and sensing technologies are mainly based on the conventional radio frequency (RF) or laser technologies. These systems suffer from several issues such as RF interference poor performance in scenarios where incidence angle between speed detector vehicle is rapidly varying. Introducing a new technology will add diversity to these enhance reliability of real-time data. In this study, we investigate our estimation system named “Visible Light Detection Ranging (ViLDAR)”....
