Análise comparativa entre as tecnologias de comunicação bluetooth e wi-fi no contexto de automação residencial.

Abstract

Home automation consists of the use of technologies to control the home environment, providing the minimization of human intervention and bringing more comfort, practicality and safety, besides promoting an efficient management of this environment. Using these technologies for automation makes the communication layer an important aspect for smart home systems. That said, it is interesting to note the existence of a diversity of communication standards, models and protocols that have the potential to be used in home control systems. Communication technologies such as Bluetooth and Wi-Fi stand out as one of the most used in this context. Thus, this work aimed to analyze the Bluetooth and Wi-Fi technologies through an experimental study involving real home automation applications, besides that, this comparative analysis allowed to explore the singularities of these communication models. For this, the Bluetooth 2.0 modules and the ESP8266-01 were subjected to a controlled experiment in a real performance scenario, in which parameters such as energy efficiency and response time were investigated to verify the existence. significant difference between such modules in the considered parameters. As a result, it was found, formally via the Mann-Whitney test, that there is a significant difference between Bluetooth 2.0 and ESP8266-01 regarding energy efficiency and performance. Another conclusion, within the scenario used for testing, is that Bluetooth proved to be a more interesting communication technology for home automation than Wi-Fi.
