Abstract:

The paper employs the thoughts of distance vector hop and average hop distance of the DV-hop location algorithm,based on principles of geometry,and a position estimation deviation is introduced to conduct the weighted centroid algorithm, leading to a novel range-free three-dimensional (3D) localization scheme. Both the principles and implementation steps of the algorithm are given. Simulation results indicate that almost all nodes could be located and that the location accuracy will be within 0.4 in the set of three-dimensional space with 40 randomly scattered anchor nodes, while the communication cost remains reasonable compared with the 2D algorithm.

Key words: sensor networks, sensor nodes, 3D-location, range-free, position estimation deviation
