Title
(EN) DETERMINATION OF COORDINATES OF A NODE IN A NODE NETWORK
(FR) DETERMINATION DES COORDONNEES D'UN NOEUD DANS UN RESEAU DE NOEUDS
Abstract
(EN) The invention relates to a method for determination of coordinates of a current node in a node network in which a message is transmitted from the current node to a subsequent node, comprising the following steps: random initialisation of virtual coordinates for each of the nodes of the network, modification of the virtual coordinates of the current node with each message transmission to the subsequent node.
(FR) L'invention concerne un procédé de détermination des coordonnées d'un nœud courant dans un réseau de nœuds dans lequel un message est transmis du nœud courant à un nœud suivant, comportant des étapes de: initialisation aléatoire de coordonnées virtuelles pour chacun des nœuds du réseau; mise à jour des coordonnées virtuelles du nœud courant à chaque transmission d'un message au nœud suivant.
