Indoor Localization using Bluetooth RSSI For Context Resolution Jason Tam Localization Algorithm Flow • Objectives • Localize Bluetooth capable smartphones indoors • Use localization for more novel context aware grouping • Results • Using test conditions: • 50 unit spacing; σ = 5; range = 100 • Approach • Client Side • Simultaneous discovery • Upload to data server • Server Side • Download data • Localize • Update GCRS Reconstruction vs. Truths • Issues • This • Many additional/missing environmental factors • Status / Future • Localization alg done when given distances • RSSI to distance conversion needs help • Integration with machine learning • Sources • [1] Indoor Location Using Trilateration Characteristics, B Cook, G Buckberry, I Scowcroft, J Mitchell, T Allen, 2005 • [2] Robust Distributed Network Localization with Noisy Range Measurements, David Moore, John Leonard, Daniela Rus, Seth Teller MIT Computer Science and Artificial Intelligence Laboratory; 2004 Example Trilateration cases http://summer.winlab.rutgers.edu/projects/wiki/2012/Projects/MobilityFirst/Context WINLAB
