TECHNIQUES FOR SUPPORTING HARMONIZED CO-EXISTENCE OF MULTIPLE CO-LOCATED BODY AREA NETWORKS

A method (400) for coordinating access to a wireless medium among multiple co-located body area networks (BANs). The method comprises detecting, by a master device of a first BAN, at least one alien BAN using beacons received from at least one co-located BAN, wherein an alien BAN is a BAN having its...

Summary:A method (400) for coordinating access to a wireless medium among multiple co-located body area networks (BANs). The method comprises detecting, by a master device of a first BAN, at least one alien BAN using beacons received from at least one co-located BAN, wherein an alien BAN is a BAN having its round start time (RST) misaligned with a RST of the first BAN (S410); recording a RST offset between the first BAN and the at least one alien BAN (S420); based on the RST offset determining which of the first BAN and the at least one alien BAN is an initiator BAN and which is a target BAN (S430); and realigning the RST of the initiator BAN with the RST of the target BAN (S460). L'invention porte sur un procédé (400) pour coordonner un accès à un support sans fil parmi de multiples réseaux corporels (BAN) colocalisés. Le procédé comprend la détection, par un dispositif maître d'un premier BAN, d'au moins un BAN étranger à l'aide de balises reçues à partir d'au moins un BAN colocalisé, un BAN étranger étant un BAN dont le temps de démarrage de cycle (RST) est désaligné avec un RST du premier BAN (S410); l'enregistrement d'un décalage de RST entre le premier BAN et le BAN étranger (S420); sur la base du décalage de RST, la détermination duquel entre le premier BAN et le BAN étranger est un BAN initiateur et lequel est un BAN cible (S430); et le réalignement du RST du BAN initiateur avec le RST du BAN cible (S460).
