Abstract

In this work I dealt with the solution of indoor localization, its design and implementation. We are at a time when the topic of smart home is a daily affair and the solution for indoor localization does not have a certain winner yet.The goal of this work is to create an intelligent presence detector, using Bluetooth technology, which recognizes in which room the device is located. And it estimates in which part of the room the device can be located.To achieve the goal, I use at least three sensors in each room and compare the signal strengths between the sensors and the localized device. A Kalman filter is used for a noise reduction on data signals from sensors.The result of the work is a functional solution for indoor localization. I have found that it is not easy to use rapidly changing signal strength within triangulation to obtain the exact position of the device. Further work could address what needs to be done to make triangulation possible and functional. One of possible directions is an exploration of Bluetooth Direction Finding technology.
