METHOD AND SYSTEM FOR LOCATION ESTIMATION

摘要

A network operating center (120) for a network (100) comprising known-location (102,104,106) and unknown-location (101,103,105) nodes can be configured to receive from each unknown-location node (101) estimates of the distances from that node to each of its neighbor nodes (102,103,104,105,106). The network controller (120) can then choose an initial location estimate for each unknown-location node (101) and compute distances from the initial location estimates to the corresponding neighbor nodes (102,103,104,105,106). The network operating center (120) 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.
