With billions in circulation around the world, the smartphone is the most important personal computing and communications device. PerfLoc was a prize competition organized by NIST for development of smartphone indoor localization apps. NIST collected a vast repository of smartphone data and made it available to the R&D community to develop indoor localization “algorithms” and to have instant, over-the-web assessment of the effectiveness of these algorithms through the NIST performance evaluation portal. The finalists achieving the best performance in the offline evaluation phase were invited to NIST to go through live testing of the smartphone “apps” they developed to implement their algorithms.
We present the structure of the PerfLoc Prize Competition and the performance achieved by the algorithms during the offline phase and the finalist apps during live testing at NIST. The results reveal what level of localization accuracy can be achieved in large buildings that had varying degrees of Wi-Fi coverage, from no coverage at all to buildings with a good density of Wi-Fi access points deployed.
Nader Moayeri has been with the National Institute of Standards and Technology (NIST) since 1997, where he founded the Wireless Communications Technologies Group and managed it for 11 years. His present research interests are in wireless networking, indoor localization and tracking, sensor networks, the Internet of Things (IoT), and Cyber Physical Systems.
He was with the Imaging Technology Department at Hewlett-Packard Laboratories, Palo Alto, CA, from 1994 to 1997 and on the faculty of the Department of Electrical and Computer Engineering at Rutgers, The State University of New Jersey, from 1986 to 1994. He received a Ph.D. in Electrical Engineering-Systems from the University of Michigan in 1986.
