Using BLE mesh network for indoor tracking

Internet of Things ger manniskor mojligheter att genom tjanster dra nytta av sensorer och andra enheter som tillsammans skapar ett brett utbud av losningar som smart hem, smart transport, aldreomsorg och mycket mer. Den senaste innovationen av Bluetooth SIG ar Bluetooth mesh topologi som tillater att ansluta tradlosa enheter i ett manga till manga forhallanden. I denna avhandling utvecklade vi ett inomhussparningssystem baserat pa Bluetooth Low Energy teknik och mesh topologi for att undersoka de potentiella fordelar som Bluetooth Low Energy natverk har att erbjuda for inomhussparningssystemet. Systemet ar utvecklat for att spara Bluetooth beacon i en inomhus kontorsmiljo. Received Signal Strength anvands for att berakna avstandet till beacon, medan positionen av beacon beraknas med Extended Min-Max och Trilateration algoritmer. Berakningar utfors pa servern. Resultaten analyseras genom jamforelse av Root Mean Square Error av bada algoritmerna. I denna avhandling utvarderas inomhussparning som en del av ett uppdrag som ges av u-blox.
