“…A VLC possui aplicac ¸ões nos mais diversos segmentos, tanto em ambientes internos, como em hospitais [3], supermercados [4], estacionamentos subterrâneos [5] e voos [6], quanto em ambientes externos, como é o caso da Internet dos Veículos (IoV -do inglês Internet of Vehicles) [7]. Quando voltada para o envio de dados entre veículos (V2V -do inglês Vehicle-to-Vehicle) e entre veículos e a infraestrutura (V2I -do inglês Vehicle-to-Infrastructure), a VLC desempenha um papel importante na troca de informac ¸ões relevantes à navegac ¸ão autônoma.…”

“…The VLC can be used in intelligent manufacturing and smart factory systems [17,18], primarily due to its low power consumption and cost; in comparison to incandescent and fluorescent fixtures [15,19]. The VLC has been applied in conference rooms [20], parking lots [21,22], aviation systems [23,24], mining areas [25], smart homes [26], and hospitals [27]. It has also been implemented in underwater scenarios [28,29] and other essential applications [30][31][32].…”

Visible light communication (VLC) has a paramount role in industrial implementations, especially for better energy efficiency, high speed-data rates, and low susceptibility to interference. However, since studies on VLC for industrial implementations are in scarcity, areas concerning illumination optimisation and communication performances demand further investigation. As such, this paper presents a new modelling of light fixture distribution for a warehouse model to provide acceptable illumination and communication performances. The proposed model was evaluated based on various semi-angles at half power (SAAHP) and different height levels for several parameters, including received power, signal to noise ratio (SNR), and bit error rate (BER). The results revealed improvement in terms of received power and SNR with 30 Mbps data rate. Various modulations were studied to improve the link quality, whereby better average BER values of 5.55 × 10 −15 and 1.06 × 10 −10 had been achieved with 4 PAM and 8 PPM, respectively. The simulation outcomes are indeed viable for the practical warehouse model. KEYWORDSVisible light communication (VLC); industrial applications; warehouse model; light fixtures; bit error rate (BER)

The Internet of Things (IoT) is a transformative technology marking the beginning of a new era where physical, biological, and digital worlds are integrated by connecting a plethora of uniquely identifiable smart objects. Although the Internet of terrestrial things (IoTT) has been at the center of our IoT perception, it has been recently extended to different environments, such as the Internet of underWater things (IoWT), the Internet of Biomedical things (IoBT), and Internet of un-derGround things (IoGT). Even though radio frequency (RF) based wireless networks are regarded as the default means of connectivity, they are not always the best option due to the limited spectrum, interference limitations caused by the everincreasing number of devices, and severe propagation loss in transmission mediums other than air. As a remedy, optical wireless communication (OWC) technologies can complement, replace, or co-exist with audio and radio wave-based wireless systems to improve overall network performance. To this aim, this paper reveals the full potential of OWC-based IoT networks by providing a top-down survey of four main IoT domains: IoTT, IoWT, IoBT, and IoGT. Each domain is covered by a dedicated and self-contained section that starts with a comparative analysis, explains how OWC can be hybridized with existing wireless technologies, points out potential OWC applications fitting best the related IoT domain, and discusses open communication and networking research problems. More importantly, instead of presenting a visionary OWC-IoT framework, the survey discloses that OWC-IoT has become a reality by emphasizing ongoing proof-of-concept prototyping efforts and available commercial off-the-shelf (COTS) OWC-IoT products.
