Title (EN) METHOD AND APPARATUS FOR DETERMINING THE LOCATION OF A NODE IN A WIRELESS NETWORK
(FR) PROCEDE ET DISPOSITIF DE DETERMINATION D'UN NOEUD DANS UN RESEAU 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, located nodes (105) having known locations are utilized to locate 'blind' nodes (200) whose location is to be determined. More particularly, a blind node (200) wishing to determine its location will measure a plurality of signal strengths between itself and a plurality of located nodes (105). Each located node's signal strength will then be adjusted based on at least one antenna gain pattern. A radio-location algorithm will then be executed on the adjusted signal-strength measurements to determine the nodes location.
(FR)L'invention concerne un procédé et un dispositif de détermination de l'emplacement d'un noeud au sein d'un système de communication. Pendant la marche, les noeuds localisés (105) aux emplacements connus sont utilisés pour localiser des noeuds « aveugles » (200) dont l'emplacement reste à déterminer. Plus spécifiquement, un noeud aveugle (200) voulant déterminer sa position va mesurer une pluralité de puissances de signal entre lui et une pluralité de noeuds localisés (105). Chaque puissance de signal de noeud localisé sera ensuite ajustée en fonction du schéma de gain d'antenne. Un algorithme de radiolocalisation sera enfin mis en oeuvre pour les relevés de puissances de signal dans le but de déterminer l'emplacement des noeuds.
