Indoor localization of students using Bluetooth low energy and wi-fi in smart libraries

The concept of smart cities, smart offices is growing with the advent of Internet of Things paradigm. Since libraries are places where students spent most of their student life, they are no exception from implementation of high-level services for enhancing the commodity and productivity of students. In recent years, the demand for a defacto indoor localization solution, as the GPS for outdoors, is constantly increasing. This thesis offers a proof of concept indoor localization system that enables smart libraries to label the appropriate study topic on map for each occupied desk. Complete developed system based on BLE and WiFi localization technology, enables students through use of Android mobile application to create working groups, transparently have knowledge of what other colleagues are studying and advertise their study topic. Through use of existing Wi-Fi infrastructure and newly deployed network of BLE beacons, the localization system consists of 3 entities (i) a client Android mobile application used by students to publish study topics or create groups, (ii) a back-end server application in charge of communication with client application through MQTT, calculation for discrete position location and providing information for (iii) a front-end server application, which is in charge of simple and nice graphical displaying of illustrated map of a library along with color labeled locations of individuals and groups categorized by their study topics. All components details are described in depth and an experimental evaluation is performed of the indoor localization system in a realistic scenario.
