Abstract
Embodiments of the present disclosure relate to making a localization map for a network. A fixed location for a plurality of wireless devices is received and a bisecting line is determined in a plane for each straight line that joins a pair of the plurality of wireless devices. An initial wireless device access sequence is assigned to each of a plurality of regions created on the localization map by the bisecting lines based on the Euclidean distance of the wireless device to the each of the plurality of regions, wherein the wireless device access sequence is the sequence of the wireless devices that provide the strongest to weakest signal to the region. Receiving from a user computing device a received signal strength (RSS) value for each signal received by the user computing device from each of the plurality of wireless devices and updating the localization map based on RSS values.
