A visible light positioning (VLP) system for multi‐cell networks based on multi‐colour LED that combines frequency division multiplexing with the received signal strength and a trilateration method is proposed. First, it employs experimental measurements to model the designed visible light communication (VLC) system under the characteristics of the...

Hoy en día, la vida es impensable sin el uso de la tecnología, pues ésta se encuentra prácticamente en todos los ámbitos, sin embargo y a pesar de las ventajas que su uso provee, todavía existen procesos que se siguen realizando de manera tradicional. Un ejemplo de esto se observa en las peleas de gallos, en las cuales aún hay muchos lugares donde...

Las Tecnologías de la Información y la Comunicación (TIC) han sido clave para que la enseñanza en línea ingresara con tal ímpetu en el mundo pedagógico que modificara el paradigma educativo. La oferta y demanda de cursos en línea se ha incrementado fuertemente los últimos años debido principalmente a dos parámetros: su menor costo con respecto a cu...

Indoor positioning systems based on visible light communication (VLC) using white light-emitting diodes (WLEDs) have been widely studied in the literature. In this paper, we present an indoor visible-light positioning (VLP) system based on red–green–blue (RGB) LEDs and a frequency division multiplexing (FDM) scheme. This system combines the functio...

En los últimos años, se ha establecido la necesidad de que las ciencias ambientales en su proceso de construcción actual, replanteen la forma de entender el consumo, que permitan generar estrategias que abonen al cambio climático. Bajo este escenario, el presente trabajo tiene como objetivo diseñar un modelo matemático que permita evaluar los consu...

Currently, wireless sensor networks (WSN) are an alternative for data control and analysis in different applications. The development of a WSN encompasses two main tasks: the design of the nodes and the development of the application for monitoring and analyzing the data collected. In this research the design and construction of a dynamic system fo...

In this paper, we introduce the Matrix‐MMC propagation model for indoor wireless optical channels. This proposed method is evolved from the modified Monte Carlo (MMC)–based ray tracing algorithm, but in addition to the properties of MMC, it has the capability of capturing reflection phenomena implying changes on wavelength (eg, fluorescence, phosph...

The feasibility of using Visible Light Communications (VLC) technology is a reality nowadays. As this technology is being inserted into the mass market, deliberation about the security provided by this technology, which is one of their main selling points, should be taken into consideration. In this paper, different scenarios of VLC sniffing are st...

So far, most of the research activity on visible light communications (VLC) technology has been focused on the communication problem, paying very little attention to the layout design and implementation conditions of practical illumination systems. Therefore, in this paper, we propose to evaluate and analyze the VLC channel effects imposed by a rea...
