Methods and systems for mobility of mobile nodes in mesh networks are taught wherein the mobile mesh nodes choose an attachment point to another mesh node based on predetermined criteria, such as the characteristics of the attachment point's path to a reference destination, and other factors local to the attachment point, such as load and available capacity. The mobile nodes forward packets on each other's behalf. Static and mobile nodes and the links between them are treated differently from each other in view of their respectively different properties. A special metric is used for paths that include mobile links in addition to the static mesh links and wired mesh links. Mobility is handled completely transparently to any client devices attached to the mesh nodes, where this attachment could be wireless or wired.

L'invention concerne des procédés et des systèmes pour la mobilité de nAEuds mobiles dans des réseaux maillés, selon lesquels les nAEuds mobiles de maillage choisissent un point de rattachement à un autre nAEud de maillage sur la base de critères prédéfini tels que les caractéristiques du trajet du point de rattachement à une destination de référence, et d'autres facteurs locaux du point de rattachement, comme la charge et la capacité disponible. Les nAEuds mobiles transmettent des paquets à la demande de chacun. Les nAEuds statiques et mobiles et les liaisons entre eux sont traités différemment les uns des autres en fonction de leurs propriétés différentes respectives. Une mesure métrique spéciale est utilisée pour des trajets qui comprennent des liaisons mobiles en plus des liaisons statiques et câblées de maillage. La mobilité est traitée de manière totalement transparente pour tous les dispositifs clients rattachés aux nAEuds de maillage, ce rattachement pouvant être sans fil ou câblé.
