Wireless sensor network (WSN) is widely used in industrial control, signal acquisition; intelligent household production and life in various aspects, such as its main communicate through wireless channel. Because of the wireless sensor network (WSN) is widely decorate, its positioning as one of the important applications. The traditional two-dimensional plane positioning has can't meet the demand. Three-dimensional positioning method has become the focus of the study, however, since most sensor nodes in wireless sensor networks are limited energy, aiming at this problem, this paper will consider under the maximum energy efficiency of localization algorithm, under the condition of ensure the positioning precision, minimize the consumption of energy, improving energy efficiency. Simulation analysis show that the proposed algorithm effectively improves the efficiency of energy utilization, and ensure that the three dimensional positioning accuracy and stability.
