Abstract
(EN) Disclosed are a method and apparatus for measuring the distance between nodes. According to a preferred embodiment of the present invention, at least N nodes are arbitrarily selected from a plurality of nodes located in a network, the N arbitrarily selected nodes are used to form n-dimensions (where N>n and n≥1), coordinates are determined for other nodes in the n-dimensions formed using the distance between the N arbitrarily selected nodes and another node, and the determined coordinates are used to calculate distances between the plurality of nodes located in the network. According to the present invention, the distance between one node and another that are located in a network can be more effectively measured.
(FR) La présente invention concerne un procédé et un appareil pour mesurer la distance entre des nœuds. Selon un mode de réalisation préféré de la présente invention, au moins N nœuds sont arbitrairement sélectionnés parmi une pluralité de nœuds situés dans un réseau, les N nœuds arbitrairement sélectionnés sont utilisés pour former des dimensions n (N > n et n ≥ 1), des coordonnées sont déterminées pour d'autres nœuds dans les dimensions n formées en utilisant la distance entre les N nœuds arbitrairement sélectionnés et un autre nœud, et les coordonnées déterminées sont utilisées pour calculer des distances entre la pluralité de nœuds situés dans le réseau. Selon la présente invention, la distance entre un nœud et un autre qui sont situés dans un réseau peut être mesurée plus efficacement.
(KO) 노드 사이의 거리 측정 방법 및 장치가 개시된다. 본 발명의 바람직한 일 실시예에 따르면, 네트워크에 위치하는 복수개의 노드들 중 적어도 N개의 노드를 임의로 선택하고, 임의로 선택된 적어도 N개의 노드를 이용하여 n차원(N>n, n≥1)을 형성하여, 임의로 선택된 적어도 N개의 노드와 다른 노드 사이의 거리를 이용하여 형성된 n차원에서 다른 노드들의 좌표를 결정하고, 결정된 좌표를 이용하여 네트워크에 위치하는 복수개의 노드들 사이의 거리를 계산한다. 본 발명에 따르면, 네트워크에 위치하는 노드와 노드 사이의 거리를 보다 효과적으로 측정할 수 있는 장점이 있다.
