Abstract

La présente invention concerne un procédé et un dispositif de gestion d'exception pour un répéteur dans un réseau de capteurs sans fil. Le procédé comprend les étapes suivantes : pendant un premier créneau temporel de réseau d'une période de balise actuelle, un point d'accès sans fil de l'Internet des objets détecte une exception d'état d'un premier répéteur, et envoie une instruction de signalisation de données de liaison montante au premier répéteur ; pendant un second créneau temporel de réseau de la période de balise actuelle, le point d'accès sans fil reçoit des données de liaison montante qui sont envoyées par le premier répéteur en réponse à l'instruction de signalisation de données de liaison montante, les données de liaison montante étant des données qui sont signalées pendant la période de balise actuelle par un terminal de l'Internet des objets sur lequel le premier répéteur est monté. Un mode de réalisation de la présente invention est avantageux en ce qu'il améliore l'intégrité d'une transmission de données, et supprime tout retard, lorsqu'un répéteur dans un réseau de capteurs sans fil est anormal.
