Title (EN) TIME SYNCHRONIZATION METHOD FOR HIGH ENERGY EFFICIENCY IN WIRELESS NETWORK AND NETWORK APPLYING SAME
(FR) PROCÉDÉ DE SYNCHRONISATION TEMPORELLE POUR HAUTE EFFICACITÉ ÉNERGÉTIQUE DANS UN RÉSEAU SANS FIL, ET RÉSEAU L'APPLIQUANT
(KO) 무선 네트워크에서의 에너지 고효율을 위한 시간 동기화 방법 및 이를 적용한 네트워크
Abstract: front page image
(EN)The present invention relates to a time synchronization method for high energy efficiency in a wireless network and a network applying the same, wherein time synchronization between sensor nodes is performed using an alternating characteristic in a low power wireless network in a sleep mode. Accordingly, it is possible to improve energy efficiency by minimizing power consumption and also improve the accuracy of time synchronization regardless of an installation location.
(FR)La présente invention porte sur un procédé de synchronisation temporelle pour haute efficacité énergétique dans un réseau sans fil, et sur un réseau l'appliquant, une synchronisation temporelle entre des nœuds capteurs étant réalisée à l'aide d'une caractéristique alternative dans un réseau sans fil basse puissance en mode sommeil. En conséquence, il est possible d'améliorer l'efficacité énergétique par réduction au minimum de la consommation d'énergie, et également d'améliorer la précision de synchronisation temporelle indépendamment d'un emplacement d'installation.
(KO)본 발명은 무선 네트워크에서의 에너지 고효율을 위한 시간 동기화 방법 및 이를 이용한 네트워크에 관한 것으로서, 슬립 모드를 적용한 저전력 무선 네트워크에서 교류 특성을 이용하여 센서 노드간에 시간 동기화를 수행하도록 하는 것이다. 이에 따라 전력소모를 최소화하여 에너지 효율을 향상시킴과 동시에 설치 위치에 관계없이 시간 동기화의 정확성을 향상시킬 수 있다.
