Performance Analysis of DF Based mixed VLC-FSO-VLC System
2020 International Conference on Signal Processing and Communications (SPCOM), 2020In this paper the performance of decode-and-forward (DF) based mixed visible light communication-free space optical communication-visible light communication (VLC-FSO-VLC) co-operative system is presented. In the proposed system, the FSO link is used for providing the outdoor connectivity and VLC environment is used for indoor connectivity.

Channel fluctuation measurement for image sensor based I2V-VLC, V2I-VLC, and V2V-VLC
2014 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2014In image sensor based VLC, transmitter acquisition and tracking are critical issue. However, the fluctuation of the VLC transmitter in the image plane caused by vehicle movement, complicates correct data reception. Therefore, in this paper, we present results of channel fluctuation measurements for infrastructure-to-vehicle VLC (I2V-VLC), vehicle-to ...

Performance Analysis of DF Based Cascaded VLC-FSO-VLC System
2020 3rd International Conference on Advanced Communication Technologies and Networking (CommNet), 2020This paper investigates the performance of decode-and-forward (DF) based cascaded visible light communication-free space optical communication-visible light communication (VLC-FSO-VLC) co-operative system. In the proposed system, the outdoor connectivity is provided by an FSO link and indoor connectivity is provided through VLC environment.

Motion modeling of mobile transmitter for image sensor based I2V-VLC, V2I-VLC, and V2V-VLC
2014 IEEE Globecom Workshops (GC Wkshps), 2014Visible light communication (VLC) using light-emitting diodes (LEDs) is drawing much attention. There are two types of VLC reception devices, a photodiode and an image sensor. VLC using image sensor is called image sensor based VLC. As the receiver only uses the image sensor pixels that sense LED transmission sources and discards other pixels ...

Vehicular VLC System With Selection Combining
IEEE Transactions on Vehicular Technology, 2022The availability of LED-based headlights and taillights makes possible the use of visible light communication (VLC) as a wireless access technology for vehicle-to-vehicle (V2V) communications. A critical concern to establish a reliable VLC link between two moving vehicles is the number of photodetectors and their locations on the destination vehicle ...

VLC-IR Dual Switching Transmission System for VLC Sensor Networks
2020 International Conference on Electronics, Information, and Communication (ICEIC), 2020In this paper, we study the dual transmission technique which uses visible light communication and IR in visible light communication IoT system. Conventional visible light communication has a problem that the communication is disconnected when visible light does not reach directly or when a shadow region occurs due to an obstacle.

Antimicrobial Properties of VLC Liners
Journal of Esthetic and Restorative Dentistry, 1990The antimicrobial activity of several visible light cured glass ionomer and liner materials against three bacteria commonly found in the oral cavity is discussed. Vitrabond light cure glass ionomer produced zones of inhibition against all the bacteria tested in this study.

Position of light sources for VLC
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017White LED diodes are increasingly used. Thanks their features they are also used for illumination and gradually replace the classical light bulbs and fluorescent tubes. The one of advantages of white LED diodes is their availability for the Visible Light Communication. This article deals with study of suitable placing of light sources for indoor.

Proceedings of the 1st ACM MobiCom workshop on Visible light communication systems, 2014
Visible light communication (VLC) is based on modulating inexpensive LEDs that are simultaneously used for illumination. This dual-use approach can offer energy-efficient connectivity as well as high throughput due to the huge unregulated optical spectrum.

Joint Power Allocation for the Multi-User NOMA-Downlink in a Power-Line-Fed VLC Network
IEEE Transactions on Vehicular Technology, 2019 Visible light communications (VLC) constitutes as a promising downlink technique of supporting the ever-increasing tele-traffic. Since the ubiquitous mains power line constitutes a natural backbone feed for VLC, a combined power line and VLC network is ...
