Developing an adaptive 3-dimensional (3D) topology control algorithm is important because most wireless nodes are mobile and deployed in buildings. Moreover, buildings, link qualities topologies change frequently due to various objects the interference from other devices. Previous algorithms can suffer significant performance degradation they only use Euclidean distance for construction. In this paper, we propose a novel 3D ad-hoc sensor networks, especially indoor environments. The proposed adjusts minimum transmit power adaptively with considering effect. To construct local topology, each node divides space, sphere centered at itself, into k equal cones by using Platonic solid (i.e., regular k-hedron) selects neighbor that requires lowest cone. Since values depend on effect of interferences, adjust preserve network connectivity reliably. evaluate algorithms, conduct experiments simulator real platforms. experimental results show superior previous terms packet delivery ratio energy consumption relatively low complexity.
