摘要：The building strategy of network topology in 3D space is important technology for wireless sensor networks (WSNs). It is often more complex to assess the detection area of sensor node in 3D terrain. The research on topological modeling method, which can withstand a certain amount of node failures and maintain work properly, has become the focus in recent years. In this paper, a 3D terrain with multi-peaks is defined by Gaussian distribution and a new scale-free wireless sensor network topology is modeled in 3D terrain. According to the improved growth and preferential attachment criteria in complex network theory and considering the limited communication radius and energy of sensor nodes, this model is tolerant against random attacks and apply to WSNs in 3D terrain.
