Abrégé
(EN)
The invention relates to a method for broadcasting beacon frames in a short-range wireless ad-hoc network including a plurality of wireless terminals. In order to improve the efficiency of the ad-hoc network in terms of power consumption, the terminal that defines the beacon interval for the network starts as a beacon broadcaster and introduces an identifier list in at least some of the beacon frames broadcast in the network. The identifier list, which includes identifiers of the wireless terminals belonging to the network, is utilized if another wireless terminal is to be selected as the beacon broadcaster.
(FR)
L'invention concerne un procédé de diffusion de trames de signaux de balise dans un réseau ad hoc sans fil de courte portée, contenant une pluralité de terminaux sans fil. Pour que l'efficacité de ce réseau soit améliorée en termes de consommation de puissance, le terminal qui définit l'intervalle des signaux de balise pour le réseau commence à fonctionner en tant que diffuseur de signaux de balise et introduit une liste d'identifiants dans au moins certaines des trames de signaux de balise diffusées dans le réseau. Cette liste d'identifiant, qui comprend des identifiants des terminaux sans fil faisant partie du réseau, est utilisée si un autre terminal sans fil doit être sélectionné en tant que diffuseur de signaux de balise.
