- © 2017, Springer Science+Business Media New York.A low-complexity vertex-projection method based on a pyramidal trilateration technique suitable for node position estimation in ad-hoc/sensor network scenarios is presented. Also a maximum likelihood position location is introduced to compare position location performance. The proposed methodology relies solely on range estimate between neighboring nodes on the connecting path linking the node of interest to the reference location access points. Feasibility is studied in the presence of measuring and routing noise and path dispersion that depend on the node density and reachability of radius. Results show that adequate proximity information can be achieved for a wide variety of multi-hop scenarios. Number of reference nodes is increased and shown that three references are sufficient for position location. Noisy environments where iid and non-iid random variables are generated are also shown, where the proposed algorithm achieves good performance in terms of the rms error position.
