(FR) PROCÉDÉ DE RÉDUCTION D'ERREUR DE POSITIONNEMENT SANS FIL DANS UN SYSTÈME À NŒUDS MULTIPLES ET TERMINAL ASSOCIÉ
(KO) 다중 노드 시스템에서 무선 측위 오차를 줄이는 방법 및 이를 위한 단말
Abstract:
(EN) The present invention provides a method for reducing a wireless positioning error by a target node in a multi-node system. Specifically, the method comprises the steps of: receiving information on the positions of anchor nodes from the anchor nodes, respectively; performing ranging of each of the anchor nodes; and when the target node is in a first state, transmitting information on the position of the target node to neighboring nodes except for each of the anchor nodes.
(FR) La présente invention concerne un procédé de réduction d'une erreur de positionnement sans fil par un nœud cible dans un système à nœuds multiples. En particulier, le procédé comprend les étapes consistant à : recevoir des informations sur les positions de nœuds d'ancrage provenant des nœuds d'ancrage, respectivement; effectuer une télémétrie de chacun des nœuds d'ancrage; et lorsque le nœud cible est dans un premier état, transmettre des informations sur la position du nœud cible aux nœuds voisins à l'exception de chacun des nœuds d'ancrage.
(KO) 본 발명에서는 다중 노드 시스템에서 타겟 노드가 무선 측위 오차를 줄이는 방법이 개시된다. 구체적으로, 상기 방법은 앵커 노드 각각으로부터 상기 앵커 노드의 위치에 관한 정보를 수신하는 단계, 상기 각각의 앵커 노드에 대한 레인징(ranging)을 수행하는 단계, 상기 타겟 노드의 상태가 제 1 상태인 경우, 상기 타겟 노드의 위치에 관한 정보를 상기 각각의 앵커 노드를 제외한 주변 노드에게 전송하는 단계를 포함한다.
