In application of wireless sensor network, the position information of sensor node is crucial within life cycle in the whole network. In order to design algorithm of node positioning with high-efficiency, high-precision and low-consumption, this paper puts forward using the encryption algorithm of space control node originally applied in field of engineering measurement, by using SDI algorithm ( space and distance intersection algorithm) as three-dimensional position algorithm used in system to achieve three-dimensional automatic positioning calculation of distributed nodes. Test proves that this kind of algorithm has better positioning nature and higher precision; it is used as three-dimensional positioning because it has good engineering application value.
