Locating sensors of a network of wireless sensors

摘要

A method and apparatus are provided for locating the positions of sensors of a network of sensors suitable for communicating with one another by radio connection. The method is suitable for receiving, from sensors of the network of sensors, measurements of relative distances between sensors of the network; for calculating a topology for the network of sensors from the received distance measurements, the topology comprising nodes representative of sensors of the network of sensors; and for determining absolute positions for the sensors by anchoring the calculated topology in an absolute frame of reference on the basis of constraints associated with an environment plan of the network of sensors. The invention also provides a locating device implementing the management method.
