Patent attributes
A method and system of broadcasting crowd-sourced localization data from a mobile device within a pedestrian area. The method, executed in the processor of the mobile device, comprises localizing the mobile device by determining an estimated position of the mobile device within the pedestrian area based on accessing fingerprint data of the pedestrian area, broadcasting, at a first broadcast power level, a localization data packet that includes data of the estimated position to one or more peer mobile devices within the pedestrian area, determining a confidence level indicative of a degree of accuracy for the estimated position, and continuing the broadcasting at one of a lower and a higher broadcast power level than the first broadcast power level when it is determined that the confidence level is one of above and below a threshold confidence level.
