Abstract
Mediante este estudio y análisis de los puntos de acceso que están localizados en el edificio 4 de la universidad se espera conseguir información suficiente que sirva como primer paso para el desarrollo de un sistema que permita la localización en interiores a través de la red Wi-Fi.
Este estudio se ha dividido en varios bloques acordes a la planificación que se ha hecho a la hora de realizar el trabajo:
Escaneo de los puntos: Se ha procedido a dividir cada planta del edificio en sectores que debían ser escaneados. Para la realización de esta parte previamente se crearon una serie de scripts que permitirán fácilmente realizar este escaneo de forma automática, así como la extracción de la parte útil de ellos que posteriormente se introduce automáticamente en la base de datos que se ha creado para el almacenamiento de la información para su posterior análisis.
Herramienta para el análisis: Se ha creado una aplicación web que sirva como apoyo visual e interactivo para el análisis de los datos, consiguiendo una mayor facilidad de acceso a la información almacenada dentro de la base de datos. También se ha usado como apoyo para el proceso de validación.
Validación de los datos: Para garantizar la consistencia y la fiabilidad de los datos que se han escaneado, se realizan una serie de pruebas para comprobar que el resultado obtenido es el esperado.
Análisis de la información: Todo lo obtenido durante los escaneos se estudia y se analiza para observar la información más relevante, tanto a nivel general como más concreto para el proyecto que nos ocupa. De forma que consigamos recopilar información suficiente para saber si es posible realizar un sistema final que permita la localización solo con la red Wi-Fi.
This essay, Captura y análisis de datos para un sistema de localización en interiores basado en Wi-Fi (Capture and data analysis for a Wi-Fi-based localization indoor system), is the first part of a bigger project. The title explains itself, the ultimate goal is to develop a localization system based on Wi-Fi. Nevertheless, for that purpose it is necessary to start doing a research about the Wi-Fi network of the university: how it is distributed, its floors, access points... Everyday more people use different kinds of media devices, which are very integrated in our lives, and more everyday. Reading books, listening to music, watching the news, doing banking operations, keeping in touch with friends or family members are some of the possibilities that these technologies offer to us and that make them be in a continuous growth. However, all of them have something in common: the use of internet connection is key for them. Thus, Wi-Fi networks —private or public— are increasing and they are used every day by more and more people. In this context, our idea of the project emerges. These Wi-Fi networks have a wide use, and this fact presents the possibility of obtaining a certain use of them, apart from the evident, which is providing wireless support to internet connections. The main goal set in our project is to create a base which will be used in the future to continue with the develop of the localization system. In order to do that, in one hand, we create the database full of information related to the access points which we will find in different locations of the university and, in the other hand, we analyze and validate all this information to guarantee that it will be useful to continue with this project in the future. Our research has been made in the Building 4 of the university, since the Department which frames the project sets there. This building has 5 floors, with different shapes and sizes each one. For the process of data collection, the location was divided in cells of 16 square meters to scan them, so the scan would be uniform and with the same gap between each of them. Then, all of the cells in which we were collecting information were numbered, so this way, each scan and the data found could be identified with its corresponding physical location...
