Abstract
On décrit un réseau maillé sans fil comprenant un maillage de dispositifs alimentés en courant continu (CPD) et un maillage de dispositifs alimentés par batterie (BPD). Les BPD sont organisés en couches de saut sur la base d'une distance de saut jusqu'au maillage de CPD. Les CPD transmettent des balises temporelles à des BPD dans une première couche de saut au cours d'une première fenêtre de réception associée à la première couche de saut. Les BPD de la première couche de saut transmettent ensuite des balises temporelles à des BPD d'une seconde couche de saut au cours d'une seconde fenêtre de réception. De cette manière, le réseau maillé sans fil propage des valeurs temporelles dans tout le maillage BPD. Sur la base de ces valeurs temporelles, les BPD s'allument dans de courts intervalles de temps pour échanger des données avec des BPD voisins, puis s'éteignent pendant des intervalles de temps plus longs, économisant ainsi l'énergie de la batterie. Ces techniques de l'invention, qui permettent d'économiser l'énergie de la batterie pour les BPD, peuvent également être appliquées pour réduire la consommation d'énergie des CPD.
