Abstract
This thesis compares approaches to the problem of discovering a mobile user's location indoors. The particular challenges of location discovery using 802.11 (Wi-Fi) signals and "organically collected" (i.e. user-generated) received signal strength maps are discussed. Several existing and novel localizer algorithms are compared on a database of organically collected data. Features of local Wi-Fi "signatures" which are relevant to location discovery are identified and applied to algorithm design considerations. Future directions for algorithm refinement are discussed.
