Abstract
A network operating center for a network comprising known-location and unknown-location nodes can be configured to receive from each unknown-location node estimates of the distances from that node to each of its neighbor nodes. The network controller can then choose an initial location estimate for each unknown-location node and compute distances from the initial location estimates to the corresponding neighbor nodes. The network operating center can then choose subsequent location estimates of the unknown-location nodes by minimizing an error criterion based on a comparison of the received neighbor node distance estimates with the computed neighbor node distances.
