Abstract

La présente invention concerne un procédé de pontage de répéteur comprenant les étapes suivantes : si une passerelle ne reçoit pas un message de rétroaction, d'un premier répéteur, durant une période de temps prédéfinie, la passerelle sélectionne un répéteur cible parmi une pluralité de seconds répéteurs, la pluralité de seconds répéteurs étant des répéteurs de secours du premier répéteur ; et la passerelle envoie une instruction de pontage au répéteur cible, l'instruction de pontage étant utilisée pour indiquer au répéteur cible d'exécuter un pontage avec le premier répéteur. Le mode de réalisation de la présente invention concerne en outre une passerelle. Le mode de réalisation de la présente invention peut maintenir un échange de données normal entre différents dispositifs dans l'Internet des objets lorsqu'une liaison d'échange de données connaît une anomalie.
