%X The spatial structure of three-dimensional (3D) sensor networks is much more complicated than that of two-dimensional (2D) sensor networks.The random structure assumption which is adopted by most of the current researchers cannot satisfy all demands of 3D sensor networks in real life.Then,three spatial symmetric cubic lattice structures were proposed.The coverage properties of them were analyzed based on the spatial tessellations theory.In addition,since previous works on random structured wireless networks used sophisticated probabilistic tools to derive their bounds,a simpler analysis technique named bin-covering was applied to get tight threshold for coverage properties of random structured 3D sensor networks.
