Indoor channel modelling and characterization for visible light communications
(IEEE, 2014)
In this paper, we investigate channel modeling for visible light communications using ray tracing approach. The simulation environment is created in Zemax® and enables us to specify the geometry of the environment, the ...
Distance and power based experimental verification of channel model in visible light communication
(IEEE, 2019)
In this work, a channel model for line-of-sight (LOS) in visible light communication is elaborated. In the proposed channel model, there is no optical component, such as filter or lens, between the transmitting LED and the ...
Emerging optical wireless communications-advances and challenges
(IEEE, 2015-09)
New data services and applications are emerging continuously and enhancing the mobile broadband experience. The ability to cope with these varied and sophisticated services and applications will be a key success factor for ...
Vehicular visible light communications with SPAD receivers
(IEEE, 2019)
Light emitting diodes (LEDs) are increasingly used in automotive exterior lighting. The expected wide availability of LED-based front and back lights makes visible light communication (VLC) a natural vehicular connectivity ...
A mobile channel model for vlc and application to adaptive system design
(IEEE, 2017-05)
In this letter, we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing, we first obtain channel impulse responses for each point over the user ...
Resource allocation for visible light communication systems using simulated annealing based on a problem-specific neighbor function
(IEEE, 2019)
In this paper, we consider a visible light communication (VLC) system with direct current-biased orthogonal frequency division multiplexing (DC-OFDM) and investigate resource allocation for a multi-user environment. Based ...
Channel modeling for visible light communications
(Springer Science+Business Media, 2016)
In this chapter, we present a novel and realistic channel modeling approach for visible light communications that overcomes to the limitations of previous works. In our work, we consider wavelength dependency, effect of ...
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 ...
VLC ağları için genetik algoritma temelli kaynak atama tekniği
(IEEE, 2017)
Bu çalışmada, görünür ışıkla haberleşme (VLC) ağları için genetik algoritma (GA) temelli kaynak atama tekniği önerilmiştir. Optik VLC agı mevcut aydınlatma altyapısının kullanıldığı iç mekanlarda çok küçük boyutlu hücrelerden ...
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 ...
