In this paper, we highlight the potential benefit of employing optical-RIS (O-RIS) for hybrid RF-VLC V2X communication networks for enhanced road safety applications, particularly at road intersections. We utilize various analytical tools of stochastic geometry to characterize the performance of the proposed framework subject to interference originating from neighbouring vehicles in terms of perfo...Show More
In this work, we showcase the potential benefit of employing optical intelligent reflecting surfaces (O-IRS) for improving safety message dissemination for vehicular visible light communication (V-VLC) systems particularly at the road intersections. Buildings, roadside structures, signboards, and other impediments commonly hinder line-of-sight (LoS) communication between vehicles at urban crossroa...Show More
Traffic safety at road intersections can be enhanced by improving opportunistic exchange of safety messages between vehicles. In urban intersection scenario, obstacles such as buildings and road side installations/signboards block the line-of-sight communication between vehicles. In order to enhance the reliability of communication link, the existing vehicular solution utilizes relay placement at ...Show More
Visible light communication (VLC) has recently emerged as an affordable and scalable technology supporting very high data rates for short range vehicle-to-vehicle (V2V) communication. In this work, we advocate the use of vehicular-VLC (V-VLC) for basic safety messages (BSMs) dissemination in lieu of conventional vehicular radio frequency (V-RF) communication in road intersection applications, wher...Show More
In this work, we explore the potential benefits and practical challenges associated with implementation of optical power domain non-orthogonal multiple access (OPD-NOMA) scheme for visible light communications (VLC) based vehicle-to-everything (V2X) networks with a major aim of providing vehicles with reliable, ubiquitous, and massive connectivity. In the proposed framework, an installed light sou...Show More
In this article, we characterize various aspects of stochastic behavior of intervehicular interference by modeling location of road vehicles as a spatial Poisson point process. We make use of various analytical tools of stochastic geometry to provide an analytical framework to access the performance for both vehicular-radio frequency (V-RF) communication and vehicular-visible light communication (...Show More
Vehicle-to-Everything (V2X) using Visible Light Communication (VLC) channels can be seen as an economically viable option to replace the existing modes of vehicular communications in the near future. In this paper, we have analyzed the performance of VLC based V2X communication under various environmental deterrents viz. Light Fog, Dense Fog, Light Smoke and Dense Smoke using a proof-of-concept te...Show More
This works analyses the performance of Visible Light Communication (VLC) based Vehicular-to-Vehicular (V2V) Communication under different weather conditions viz. dense fog, light fog, wet snow, dry snow, rain etc. while considering the effect of interference from nearby vehicle. The performance has been evaluated by obtaining both quantitative as well as qualitative results. Through the obtained r...Show More
This paper investigates the performance of hybrid RF-Solar harvesting circuit that can simultaneously harvest power from solar and radio frequency (RF) sources readily available in the surrounding environment. The proposed work utilizes stand-alone RF and solar harvester circuits to realize a hybrid harvester circuit. The stand-alone RF harvester circuit is a dual-band multi-stage harvester that h...Show More
The latest trend in lightwave communication system is towards huge information transmission capacity by explosive growth in data rate communication. Wavelength division multiplexing is used to achieve this objective. It is a technology of transmitting data from different sources over a single link at same time whereas each data channel is carried on its own unique wavelength. Dense WDM is evolved ...Show More
Optical code division multiple access (OCDMA) systems allow several users to access a medium simultaneously without any contention. Each user is assigned a unique code which is orthogonal to all other codes assigned to various users in the system. In this paper we studied the effect of different combination of codes and detection techniques for spectral-amplitude coding optical code-division multi...Show More
