Claim:
1. A method for making a localization map for a network, the method comprising: receiving, by a computer, a fixed location on a plane for each of a plurality of wireless devices; for each straight line that joins a pair of the plurality of wireless devices, determining, by the computer, a line in the plane that bisects the joining line at an initial predetermined angle; assigning, by the computer, an initial wireless device access sequence 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, by the computer, from a user computing device at a known location, 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, by the computer, the localization map based on RSS values, wherein the updating, by the computer, the localization map based on the RSS values, further comprises: determining, by the computer, which of the bisecting lines on the localization map needs to be updated based on whether the initial wireless device access sequence of the known location accurately reflects the received RSS values at the known location; and updating, by the computer, the bisecting line on the localization map to reflect the received RSS values.
