1. A method for determining a node's location within a communication system, the method comprising the steps of: (a) determining a plurality of distances to nodes within the communication system based on first channel-model parameters; (b) producing a first location of the node based on the first set of distances; (c) calculating new channel-model parameters based on the nodes location; (d) recalculating the plurality of distances to nodes within the communication system based on the second channel-model parameters; and (e) producing a second location of the node based on the recalculated distances.
