Abstract:
1. A method of assigning wireless nodes, which are in a derivable spatial arrangement, to positions in an array of positions, the wireless nodes being in communication with each other and with a control processor, the method comprising: receiving, at the control processor from each wireless node, a range determined by the wireless node between itself and each other wireless node; deriving, at the control processor, the spatial arrangement of the wireless nodes in relation to the array of positions, based on the range received from each wireless node, wherein the array of positions is unknown to the wireless nodes and known to the control processor, said deriving realized by: building a decision tree to represent a hypothesis for the assignment of a first of said nodes to a first of said positions; extending said decision tree to represent hypotheses for the assignment of each further node to a plurality of said positions; assigning a probability to each of said hypotheses, wherein the probability is based on the spatial arrangement of the wireless nodes; selecting one of said positions for each of said nodes based upon the probabilities of said hypotheses and assigning each of said nodes to its selected position.
