PROCÉDÉ ET SYSTÈME ET DISPOSITIF DE NŒUD POUR LOCALISER DES INFORMATIONS DISPONIBLES AU NIVEAU D'UN DISPOSITIF DE NŒUD DANS UN RÉSEAU DE DISPOSITIFS DE NOEUD INTERCONNECTÉS EN COMMUNICATION

摘要

A node device (4) in a network (1) of communicatively interconnected node devices (4) having limited data processing and storage resources, such as a mesh network (1) of node devices (4), receives an inquiry message of the type 'find the best match' for information to be located at a node device (4). The inquiry message comprises benchmark data relating to the information to be located. The receiving node device updates the message based on a comparison of the content in the latest received message and the node's locally stored information. The locally stored information is derived from previous received messages from other node devices (4) in the network (1) and information available at the receiving node device. When no update is required, no message is broadcasted by a node device (4) and the local copy at the node devices involved converges in a few broadcasts to a static content from which the information sought can be located in the network (1).
