Estudio de una red de sensores inalámbricos con tecnología Wi-Fi y radiofrecuencia, aplicado a un sistema de control domótico inteligente distribuido

Abstract

n this degree work, we developed a survey about a wireless sensor network based on 32-bit microcontrollers and low-cost components, for home automation applications, through the development of network prototype nodes that allow us to verify experimentally and analytically the efficiency of the chosen network architecture, as the implemented communication protocols to give dynamism, flexibility and scalability to the system. To perform the above mentioned, we carried out a correlational investigation with a quantitative approach, and we applied bibliographic and experimental methods. The first one let us to understand the most important features of the wireless sensor networks and the most used standards in this area, while the second one allowed us to evaluate some important system parameters, quantitatively, to define the response time of the system, its reorganizational capacity, and to verify that the chosen architecture was the right one. As a result of this work, we implemented a wireless network with two parent nodes communicated by Wi-Fi, which one of them has five child nodes communicated by RF; and we did different tests, which allowed us to determine low response times with a high efficiency ratio in the data reception, making this network appropriated for smart home automation systems.
