Title (EN) METHOD, DEVICE AND SYSTEM FOR ASSIGNING CHANNELS IN WIRELESS MESH NETWORKS
(FR) PROCÉDÉ, DISPOSITIF ET SYSTÈME POUR ATTRIBUER DES CANAUX DANS DES RÉSEAUX MAILLÉS SANS FIL
Abstract:
(EN) A method for assigning channels in a wireless mesh network includes: creating channel assignment from initial topology of the network by iteratively determining a bottleneck node and expanding a channel; mer ging the channels of the chan nel assignment according to the occupancy of each channel until channel number of the channel assignment is equal to the maximum number of channels; distributing the merged channel assignment to the network. The present invention further discloses a device and a sy stem for assigning channels in a wireless mesh network. The requirement for planning of the frequency/radio assignment is given a tech nical solution.
(FR) L'invention concerne un procédé pour attribuer des canaux dans un réseau maillé sans fil comprenant : la création d'une attribution de canaux à partir d'une topologie initiale du réseau par la détermination itérative d'un nœud d'étranglement et l'extension d'un canal; la fusion des canaux de l'attribution de canaux selon l'occupation de chaque canal jusqu'à ce que le nombre de canaux de l'attribution de canaux soit égal au nombre maximal de canaux; la répartition de l'attribution de canaux fusionnée sur le réseau. La présente invention concerne également un dispositif et un système pour attribuer des canaux dans un réseau maillé sans fil. Le besoin de planification de l'attribution de fréquences/liaisons radio bénéficie d'une solution technique.
