SARTHI: A Secure, Accurate, Real-Time, and Heterogeneity-Resilient Indoor Localization Framework with Smartphones

Abstract: Indoor localization is an emerging internet-of-things (IoT) application domain that is poised to
reinvent the way we navigate in various indoor environments. Ubiquitously available Wi-Fi signals
have enabled low-cost fingerprinting-based localization solutions that can work with commodity
smartphones. However, fingerprinting based indoor localization frameworks face several challenges
such as mobile device resource limitations, device heterogeneity, indoor environment uncertainties,
wireless signal variations, and security vulnerabilities. These factors reduce the accuracy, reliability,
predictability, and energy-efficiency of indoor localization frameworks and represent a major barrier in
solving the localization problem in real-world settings. To counter these challenges, this thesis
proposes a novel framework for energy-efficient, real-time, and robust indoor localization that utilizes
deep learning and statistical techniques, which are prototyped and validated on a variety of handheld
mobile devices.
