Research on Three-Dimensional Localization Algorithm in Wireless Sensor Network

As a kind of brand-new information acquisition and the processing technology, the wireless sensor network has great significance in application and scientific research in many fields. But the node localization information plays a key role in the application of wireless sensor network. In view of the present situation that the two-dimensional plane node localization algorithm is difficult to be practiced in the three-dimensional space, three-dimensional localization algorithm (TDLA) has been proposed in this paper. Simulations indicate that TDLA can carry out localization on sensor node in the three-dimensional space effectively and turns to be one kind of localization methods which can be applicable.
