ViLDAR-Visible light sensing-based speed estimation using vehicle headlamps
(IEEE, 2019-11)
The introduction of light emitting diodes (LED) in automotive exterior lighting systems provides opportunities to develop viable alternatives to conventional communication and sensing technologies. Most of the advanced ...
Unmanned-aerial-vehicle-assisted cooperative communications for visible light communications-based vehicular networks
(SPIE, 2019-08)
We propose and investigate cooperative visible light communications (VLC) enabled vehicular network architecture with an unmanned aerial vehicle (UAV) relay. In the proposed system, a UAV equipped with an onboard photodetector ...
Performance evaluation of vehicle-to-vehicle visible light communications in the presence of denial of service attacks
(IEEE, 2019-06)
Visible Light Communication (VLC) has been proposed as an efficient vehicle-to-vehicle (VLC) connectivity solution for Intelligent Transportation Systems. By using the preexisting hardware in vehicles (headlights and ...
Performance characterization of underwater visible light communication
(IEEE, 2019-01)
In this paper, we investigate the performance limits of underwater visible light communication (UVLC) systems. We first develop a closed-form path loss expression as a function of transceiver parameters and water type. We ...
Efficient resource allocation scheme for multi-user hybrid VLC/IR networks
(IEEE, 2019)
An optimal fair resource allocation (OFRA) scheme is proposed to mitigate both inter-symbol and inter-user interferences in uplink multi-user VLC/IR networks. The scheme aims to improve the fairness among the users in terms ...
Diversity gain analysis of underwater vertical MIMO VLC links in the presence of turbulence
(IEEE, 2019)
To satisfy the demands of high data rate underwater applications such as image and real-time video transmission, underwater visible light communication (UVLC) has emerged as an alternative to acoustic signaling. One of the ...
Vehicle-to-vehicle visible light communication: How to select receiver locations for optimal performance?
(IEEE, 2019)
Visible light communication (VLC) utilizes vehicle headlights as wireless transmitters and has emerged as a strong candidate for vehicle-to-vehicle (V2V) communications. In majority of works on V2V VLC systems, a common ...
Vertical underwater VLC links over cascaded gamma-gamma turbulence channels with pointing errors
(IEEE, 2019)
Underwater visible light communication (UVLC) is a high capacity wireless connectivity solution with low latency, particularly appealing for real-time underwater video and image transmission. While attenuation and geometrical ...
FPGA based DCO-OFDM PHY transceiver for VLC systems
(IEEE, 2019)
Satisfying the demand for high bandwidth and low latency in Visible Light Communication (VLC) systems is a difficult challenge. VLC channels exhibit frequency-selectiveness at peak-speeds. This phenomenon generates a serious ...
A path loss model for vehicle-to-vehicle visible light communications
(IEEE, 2019)
The increasing adoption of LEDs in exterior automotive lighting makes visible light communication (VLC) a natural solution for vehicular networking. In this paper, we consider a vehicle-to-vehicle link and propose a path ...
