Abstract

La présente invention concerne un procédé de réglage automatique d'un réseau de commande IoT et un système associé, caractérisé en ce qu'une passerelle diffuse un signal de balise vers les environs ; un nœud qui a reçu le signal de balise transmet un message de demande d'enregistrement primaire demandant une connexion de communication avec la passerelle ; lorsqu'un nœud de trou de couverture qui n'a pas reçu le signal de balise reçoit le message de demande d'enregistrement primaire, le nœud de trou de couverture transmet un message de demande d'enregistrement secondaire au nœud qui a transmis le message de demande d'enregistrement primaire ; la passerelle ou un serveur séparé détermine un itinéraire pour la connexion du nœud de trou de couverture sur la base d'informations d'itinéraire collectées à partir des messages de demande d'enregistrement ; et la passerelle ou le serveur séparé transmet un message de réglage d'itinéraire pour régler le trajet déterminé à l'étape de détermination d'itinéraire. La présente invention a pour effet qu'il est possible de rechercher rapidement un nœud de trou de couverture situé dans un trou de couverture où il est impossible d'établir une connexion de communication directe avec une passerelle dans un réseau de commande IoT, de telle sorte que le réseau de commande IoT peut être configuré rapidement et automatiquement.
