Abstract

L'invention concerne un procédé et un système de commande de nœud dans un réseau maillé sans fil, ainsi qu'une puce, un dispositif électronique et un support de stockage. Le procédé comprend les étapes suivantes : un premier nœud de réseau maillé commute d'un mode de fonctionnement vers un mode à faible consommation d'énergie, le premier nœud de réseau maillé étant dormant dans le mode à faible consommation d'énergie pendant une première durée prédéfinie dans une période de balayage, et effectuant un balayage d'interface radio pendant la durée restante de la période de balayage ; et le premier nœud de réseau maillé envoie un message de notification à un second nœud de réseau maillé, le message de notification servant à indiquer que le premier nœud de réseau maillé utilise actuellement le mode à faible consommation d'énergie, et le message de notification servant également à indiquer un moyen d'envoi de données du second nœud de réseau maillé. Dans le procédé de commande de nœud selon le mode de réalisation de l'invention, un premier nœud de réseau maillé peut commuter vers un mode à faible consommation d'énergie et peut être dormant pendant une durée prédéfinie dans une période de balayage, ce qui permet de réduire la consommation d'énergie du premier nœud de réseau maillé et de prolonger le temps de service du premier nœud de réseau maillé.
