Title (EN) METHOD FOR IMPROVED TOPOLOGY MAPPING IN WIRELESS COMMUNICATION NETWORKS
(FR) PROCÉDÉ DE CARTOGRAPHIE DE TOPOLOGIE AMÉLIORÉE DANS DES RÉSEAUX DE COMMUNICATION SANS FIL
Abstract: front page image
(EN)A method is provided for enabling a base station to infer a compact topology graph among a set of mobile nodes in its cell, the mobile nodes having a secondary radio to enable inter-nodal communication. This methodology ensures that nodal membership information is gathered within approximately 100 ms, and additional topology information is gathered from all the mobile nodes within approximately 300 ms over Wi-Fi radios. In dense networks, this time can be reduced to within 100 ms.
(FR)L'invention porte sur un procédé pour permettre à une station de base d'inférer un graphe de topologie compact parmi un ensemble de nœuds mobiles (MN) dans sa cellule, les nœuds mobiles comprenant une radio secondaire pour permettre une communication internodale. Cette méthodologie assure que des informations d'appartenance nodale sont collectées en moins d'environ 100 ms, et des informations de topologie supplémentaires sont collectées en provenance de tous les nœuds mobiles en moins d'environ 300 ms sur des radios Wi-Fi. Dans des réseaux denses, ce temps peut être réduit à moins de 100 ms.
