Abstract
A method of determining the location of nodes in a wireless network, the method comprising the steps of: 1 ) establishing wireless communication between nodes to obtain range measurements between a new node (4) and at least three reference nodes (1 , 2, 3); 2) determining the locations of points of intersection (A, B) of circles representing the range measurements, each circle being centred on an associated reference node and having a radius representative of the range measurement obtained between that reference node and the new node; 3) enumerating valid combinations of points of intersection; 4) for each enumerated combination, calculating a metric related to distances between the points of intersection in the combination; 5) selecting the combination having the lowest metric; and 6) determining the position of the new node using the selected combination.
