Abstract
A three-dimensional( 3 D) wireless tomography localization method based on wireless sensor networks( WSNs) is proposed. 3 D tomographic image is reconstructed
by establishing the received signal strength( RSS)shadow fading model and the ellipsoid weight model
so as to position information of target obtain 3 D
which provide an effective algorithm for 3 D localization of target. Field experiments prove that the 3 D positioning algorithm is feasible and effective.
