Abstract
Hoy en día vivimos en una sociedad que cada día se rodea de más tecnología y aparatos electrónicos que facilitan el día a día. La gran parte de los dispositivos que se usan en la vida cotidiana se conectan a internet, lo que permite que los usuarios se puedan comunicar de manera inmediata desde casi cualquier parte del mundo y por diferentes vías tanto entre personas como personas con dispositivos o dispositivos con dispositivos. El deseo de controlar automáticamente y de forma remota de muchos de los sistemas que se utilizan de forma regular ha dado lugar a la aparición del Internet de las cosas o IoT (del inglés, Internet of Things). En el IoT todos los dispositivos están conectados entre ellos y son capaces de intercambiar información entre ellos con el objetivo de realizar una tarea concreta.
El desarrollo del IoT ha generado que se implementen nuevos dispositivos y tecnologías que permitan la optimización de su funcionamiento. También, el creciente interés de algunos usuarios por el conocimiento del funcionamiento de estos sistemas ha generado aparatos y programas al alcance de personas no profesionales.
Este trabajo presenta el panorama actual de los chips de bajo coste al alcance de una gran parte de la población y analiza distintos tipos de redes de IoT implementadas con dispositivos ESP8266. Se ha realizado una comparativa entre dos topologías, mesh y estrella, combinadas con con dos protocolos cada una: MQTT y TCP. Una vez analizados los resultados de la misma, se ha desarrollado un ejemplo de un caso real de aplicación con una de las redes analizadas. En concreto, se trata de un sistema domótico que detecte posibles anomalías en el comportamiento del inquilino con el objetivo de proporcionar ayuda si es necesario.
Nowadays we live in a society where we are surrounded by technology and electronic devices that make day-to-day life easier. Most of the devices that are used in daily life are connected to the Internet, which allows users to communicate between themselves and also enables devices to communicate between them from almost anywhere in the world. The desire to automatically and remotely control many of the systems used frequently has led to the emergence of the Internet of Things (IoT). In the IoT all devices are connected to each other and are able to exchange information between them in order to perform a specific task. The development of the IoT has generated the implementation of new devices and technologies to optimize its operation. Also, the growing interest of some users for the knowledge of the operation of these systems has generated devices and programs within the reach of non-professionals. This paper presents the current state of low cost chips within the reach of a large part of the population and analyzes different types of IoT networks implemented with ESP8266 devices. A comparison has been made between mesh and star topologies, which are combined with MQTT and TCP protocols, respectively. In addition, an example of a real application case of one of the analyzed networks has been deployed. Specifically, it is a home automation system that detects possible anomalies in the behavior of the tenant with the aim of providing assistance if necessary.
