Abstract

L'invention concerne un nud alimenté par une batterie dans un réseau maillé sans fil qui maintient un mappage entre la température et une dérive d'oscillateur et qui compense la dérive de l'oscillateur sur la base de ce mappage. Lorsque le mappage comprend des points de données insuffisants pour mapper la température actuelle et une valeur de dérive d'oscillateur, le nud alimenté par une batterie demande des paquets d'étalonnage en provenance d'un nud adjacent en amont dans le réseau. Le nud adjacent transmet deux paquets d'étalonnage avec un delta de temps de transmission et indique également ce delta de temps dans le premier paquet d'étalonnage. Le nud alimenté par une batterie reçoit les deux paquets d'étalonnage et mesure le delta du temps de réception. Le nud alimenté par une batterie compare le delta du temps de transmission au delta du temps de réception pour déterminer la dérive de l'oscillateur par comparaison avec un oscillateur dans le nud adjacent. Le nud alimenté par une batterie met ensuite à jour le mappage sur la base de la température actuelle et de la dérive de l'oscillateur déterminée.
