Diseño de un sistema de posicionamiento para interiores, desarrollado en el sistema operativo Android, basado en señales Wi-Fi, con fines turísticos realizado en el edificio Maxwell de la USFQ.

摘要

This project aims to design and develop two applications based on the Android platform to be able to identify the position of a user on the third floor of Maxwell building at the University San Francisco de Quito.The first method called Footprint scans the received power in each point of the area to cover, these samples are stored on the device, then the system compares the previous powers with the new ones that scan the device, to determine the position of the user.The other application, called Matrix H uses a path loss model to determine the distance between the router and the mobile device, called the pseudorange. From this result and the algorithm used in GPS system, called matrix H, the system determines the position of the user.Several tests were conducted, for each of the algorithms used in this project, such as: error in the calculated distance in an ideal environment, with movement and interference.
