Title (EN) METHOD AND APPARATUS FOR DETERMINING THE LOCATION OF A NODE IN A WIRELESS SYSTEM
(FR) PROCEDE ET APPAREIL PERMETTANT DE DETERMINER L'EMPLACEMENT D'UN NOEUD DANS UN SYSTEME SANS FIL
Abstract: front page image
(EN)A method and apparatus for determining the location of a node within a communication system is provided herein. During operation, reference nodes (1O5) having known locations are utilized to locate 'blind' nodes (104) whose location is to be determined. More particularly, a blind node (104) wishing to determine its location will measure a plurality of path losses between itself and a plurality of reference nodes (105), These reference nodes' locations will then be mathematically weighted by the path loss between these reference nodes (105) and the blind node (104). The location of the blind node (104) is a sum of the mathematically weighted reference nodes' locations.
(FR)L'invention concerne un procédé et un appareil permettant de déterminer l'emplacement d'un noeud dans un système de communication. En fonctionnement, des noeuds de référence (105) présentant des emplacements connus sont utilisés pour localiser des noeuds 'aveugles' (104) dont l'emplacement doit être déterminé. Plus particulièrement, un noeud aveugle (104) désirant déterminer son emplacement mesure une pluralité d'affaiblissements de propagation entre lui-même et une pluralité de noeuds de référence (105). Ces emplacements de noeuds de référence sont ensuite pondérés mathématiquement par l'affaiblissement de propagation entre lesdits noeuds de référence (105) et le noeud aveugle (104). L'emplacement du noeud aveugle (104) est la somme des emplacements des noeuds de référence pondérés mathématiquement.
