Implementation of visible light communication (VLC) for vehicles

2016 International Conference on Advanced Communication Control and Computing Technologies (ICACCCT), 2016
In this paper, a system is designed especially to communicate between vehicles at night time. This system providing a security for the driver by giving him the luxury of communicating with other vehicles without getting out of his vehicle and another important feature of this system is that for the communication purpose no service provider is needed ...

Enhancing mobile device peripheral controls using Visible Light Communication (VLC)

2015 9th International Conference on Sensing Technology (ICST), 2015
Since its emergence, Optical communication systems have always been considered as a significantly attractive alternative to wired data transfer techniques, especially in environment where high data rate is essential in a multi-component system. Unfortunately, optical communication is still not as robust as traditional mechanisms and suffers from ...

Resource Allocation for Hybrid Visible Light Communications (VLC)-WiFi Networks

2021 9th International Conference on Communications and Broadband Networking, 2021
Resource allocation management is the key issue of the integrated network of VLC and WiFi. In this paper, we discussed the existing resource allocation algorithms, and proposed a novel resource allocation algorithm based on the proportional fairness (PF) algorithm, which improved the ability of users to obtain resources in different regions and ...

Tuneable and portable lighting system for Visible Light Communications (TP-VLC)

2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015
This work presents a low cost prototype implementing new IEEE 802.15.7 standard for Visible Light Communications. A commercial off-the-shelf development platform is used to implement the firmware controlling the system. The system is tested with different LED luminaires and distances achieving data rates of 100 kbit/s with Bit Error Rates between (10−7

APPLICATION OF VISIBLE LIGHT COMMUNICATION (VLC) INVARIOUS AREAS: SURVEY

Suleyman Demirel University Bulletin Natural and Technical Sciences
Optical wireless communication allows communication of ultraviolet, infrared, or visible light to carry a signal. Visible light communication (VLC) is a member of optical wireless communication that operates in visible band from 390 nm to 750 nm range. VLC uses light emitting diodes (LED) that is pulsed at very high speed.

PAM-4 Modulator-Demodulator Design Modeling for Visible Light Communication (VLC)

2019 International Symposium on Electronics and Smart Devices (ISESD), 2019
PAM modulation has an advantage of simplicity but high throughput. Therefore, it is suitable for Real-Time VLC System. This paper aims to present a modulator and demodulator modeling design using PAM-4 for Visible Light Communication. The design is done for both transmitter and receiver. In order to reduce BER (Bit-Error Ratio), we also design the SRRC

Dynamic Resource Allocation for Visible Light Communications (VLC)- WiFi Heterogeneous Systems

2019 29th International Telecommunication Networks and Applications Conference (ITNAC), 2019
Visible Light Communication (VLC) systems are becoming an effective means of wireless communication with the potential to provide dense and fast connectivity at low cost. In this paper, we consider a VLC-WiFi heterogeneous system and investigate dynamic resource allocation for a multi-user environment to maximize the downlink capacity.
