Developing a 3D topology control algorithm to reduce interference is important. Because wireless sensor networks are often deployed in 3D space (such as multi-floor building, forest or underwater) and interference imposes a negative impact on prolonging network lifetime in wireless sensor networks. In this paper, we analyze existing 3D topology control algorithms, and the discussion shows that existing 3D topology control algorithms can not reduce interference effectively. We propose an Interference-Reducing Topology Control (IRTC) for 3D wireless sensor networks. In IRTC, each node adjusts its transmitting range to choose proper neighbors according to the cost of distance and interference to construct the local topology. We prove that the graph induced by IRTC is an energy-t-spanner of the original graph, which is extremely useful for prolonging the lifetime of the network. Simulations results show that IRTC performs 2 similar to 5 times better than existing 3D topology control algorithms in interference reduction.
