Abstract

La présente invention concerne un procédé de migration de terminal de l'Internet des objets, destiné à être utilisé dans un système de l'Internet des objets, le système de l'Internet des objets comprenant une passerelle et X répéteurs connectés à la passerelle, X représentant un nombre entier supérieur à 1, et comprenant : si la passerelle n'a pas reçu un premier message de rétroaction d'un premier répéteur au cours d'une première durée, la passerelle détermine un second répéteur en fonction d'une règle de gestion d'exception de liaison prédéfinie ; et la passerelle fait migrer un terminal de l'Internet des objets, porté par le premier répéteur, jusqu'au second répéteur. Conformément aux modes de réalisation, la présente invention concerne également une passerelle. Les modes de réalisation de la présente invention peuvent résoudre le problème de maintien d'un échange de données normales entre des objets lorsqu'il existe un défaut de liaison d'échange de données.
