摘要:Node-localization is one of the key technologies of wireless sensor networks, and mobile-anchor assisted localization method is a promising method of saving network cost. The path planning of mobile anchor is a basis of this method. For the wireless sensor networks deployed in 3-dimensional space, five deterministic paths named by Layered-Scan, Layered-Curve, Triple-Scan, Triple-Curve and 3D-Hilbert are proposed that can cover a given cubic region of interest entirely. Taken weighted centroid localization method as example, detailed simulations are performed with difference parameters. The results show that all of these five paths are better than random moving path, and 3D-Hilbert is the best path with shortest length and minimal average localization error. © 2012 Binary Information Press.
