Abstract
A method of tracking a location of a mobile device based on measurements of beacon signals transmitted between the mobile device and wireless reference nodes of a localization network. The method comprises: detecting motion of the mobile device; repeatedly applying a tracking algorithm to track the location of the mobile device, wherein the tracking algorithm is configured to estimate a current location of the mobile device by taking into account both (A) a current set of measurements of the beacon signals transmitted between the mobile device and at least some of the reference nodes and (B) one or more past sets of said measurements transmitted between the mobile device and at least some of the reference nodes; and adapting the tracking algorithm by, in dependence on the detected motion of the mobile device, adapting a relative significance attributed to the one or more sets of past measurements relative to the current set of measurements and by adapting the time-density of the beacon signals in dependence on the detected motion of the mobile device.
