RESEAU DE CAPTEURS RECONFIGURABLE

A method for reconfiguring a network of wireless sensors in which certain nodes, referred to as coordinating anchors, emit beacon signals, and others, referred to as subordinated anchors, receive the signals only for synchronisation purposes. The whole network synchronises from peer to peer via wireless links from a primary anchor, the various nodes being further configured, via an auxiliary channel, from a central server. When a node loses its synchronisation, one or more subordinated anchors can be transformed into coordinating anchors by the central server so as to restore the synchronisation of the node. Likewise, when an electronic tag moves through the network, subordinated anchors can be transformed dynamically into coordinating anchors in order to ensure the synchronisation of the tag.
