Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Wireless Sensor Networks Using Sub-Pixel Optical Camera Communications: Advances in Experimental Channel Evaluation

“…VLP systems are robust in enclosed spaces and have been explored in outdoor vehicular settings [ 25 ] where more precision than provided by satellite localization means is needed. Furthermore, positioning systems relate to another important application, intelligent transportation systems (ITS), which has been proposed as an application of VLC [ 23 , 26 , 27 , 28 ]. ITS aim to improve road safety and the communication between vehicles and infrastructures.…”

An Artificial-Noise-Based Approach for the Secrecy Rate Maximization of MISO VLC Wiretap Channel With Multi-Eves

“…Compared to the conventional radio frequency (RF) technology, it offers several advantages including the low cost in implementation and abundance in spectrum resources [1]. Recently, VLC has achieved rapid developments in many research fields, such as indoor localization [2], [3], vehicle to vehicle (V2V), vehicle to things (V2I) communication [4] and transceiver design [5], etc. In existing literatures, VLC systems can provide data rates up to a level of giga-bits [6], which satisfies the requirement of future wireless networks with high transmission speed.…”

Common-mode noise filtering with space-divided differential 2x2 VLC for V2V applications

“…As modern vehicles are tending to use LED headlights (Jong-Ho et al 2013;Uysal 2015) and LED taillights, this provides a range of automotive VLC-V2V opportunities (Kim et al 2014;Siddiqi et al 2016). As the transmission channel has time-variant properties and greatly depends on weather and visibility conditions Chen et al (2016), there are many studies available where the VLC-V2V channel is modeled (Uysal 2015;Alsalami et al 2019;Eldeeb et al 2019;Karbalayghareh et al 2020;Lee et al 2012). There are also studies on the specific impact of some dedicated weather conditions (e.g.…”

“…In most cases, a Line-of-Sight (LOS) transmission is assumed. There are also studies on non-LOS cases, discussed in , with an amount of attenuation caused by weather and other environmental effects (Karbalayghareh et al 2020;Eso et al 2019;Singh et al 2019). The VLC-V2V channel is substantially affected by natural ambient light, sun irradiance Islim et al (2018) and artificial light sources: traffic lights, public lighting, other VLC interference from nearby vehicles or objects (Beshr et al 2015;Chung and Oh 2013).…”
