Indoor localization is an emerging application domain that promises to enhance the way we navigate in various indoor environments, as well as track equipment and people. Wireless signal-based fingerprinting is one of the leading approaches for indoor localization. Using ubiquitous Wi-Fi access points and Wi-Fi transceivers in smartphones has enabled the possibility of fingerprinting-based localization techniques that are scalable and low-cost. However, the heterogeneity of Wi-Fi hardware modules and software stacks used in smartphones nowadays introduces problems when employing Wi-Fi-based fingerprinting methodologies across devices, hence diminishing the accuracy of localization. Through this chapter we propose a framework called SHERPA that enables efficient porting of indoor localization techniques across mobile devices, to maximize accuracy. An in-depth analysis comparing two variants of our proposed framework proves that it can deliver up to 8× more accurate results as compared to state-of-the-art localization techniques for a variety of environments.
