CA 2667601

A system and corresponding method using a cooperative localization technique for self identifying a location of a wireless device in a wireless network is presented. The system may estimate an arbitrary signal metric as a function of a signal received by the wireless device from the at least one other wireless device in the wireless network. The system may also convert at least one belief representing a distribution of at least one possible location of the at least one other wireless device to generate at least one converted belief. The system may further determine a self-belief as a function of the at least one converted belief and identify a self location, as a function of the self-belief, within the wireless network.

L'invention concerne un système et un procédé correspondant utilisant une technique de localisation coopérative pour identifier automatiquement l'emplacement d'un dispositif sans fil dans un réseau sans fil. Le système peut estimer une mesure de signal arbitraire en fonction d'un signal reçu par le dispositif sans fil à partir du ou des autres dispositifs sans fil du réseau sans fil. Le système peut également convertir au moins une croyance représentant une distribution d'au moins un emplacement possible du ou des autres dispositifs sans fil pour générer au moins une croyance convertie. Le système peut en outre déterminer une croyance automatique en fonction de la ou des croyances converties et identifier un emplacement automatique, en fonction de la croyance automatique, dans le réseau sans fil.
