Abstract

Localization has gained priority in an increasingly inter-connected world. The majority of industries and sectors require some means of tracking the location of objects and/or people anywhere on the Earth, whether indoors or outdoors. GPS is an already-implemented and viable solution for outdoor localization. However, indoor localization is more challenging to implement and thus has become a broad area of research. Despite the challenges of tracking location in places where satellite GPS signals are unreliable or unreachable (i.e. within a building or structure), there has been considerable progress made in indoor localization research. Although current indoor localization technology can achieve certain accuracy, they usually requires extra equipment and thus can be too cumbersome and/or expensive for common purposes. A relatively new field of indoor localization research involves using the sensors built into smartphones to triangulate a user’s position within a structure. This eliminates the requirement for extra cumbersome sensors or accessories. This honors thesis surveys the current sphere of smartphone-based indoor localization research, analyzing the state-of-the-art approaches, their benefits and drawbacks. A test-bed is also developed to facilitate the evaluation of each method mentioned in this thesis.
