Abstract
Recent researches on indoor localization have achieved the success of localizing a device within tens of centimeters accuracy. Most of the cases it requires special infrastructures, external hardware support or a lot of finger-printings via huge training or crowdsourcing about the surroundings in order to achieve this accuracy. This paper presents MuSLoc, a low cost indoor localization system which is able to achieve high accuracy in localizing regular commercial mobile devices without help of fingerprinting, infrastructure or external hardware support. MuSLoc emulates regular antenna arrays of mobile devices with specially configured MUSIC algorithm over synthetic aperture radar (SAR) in order to find the direction of arrival (DoA). Finally, it is integrated with a novel heuristic location search algorithm, named HeLE which outperforms traditional methods in indoor localization.
