In this paper, the authors propose an efficient range free localization scheme for large scale three dimensional wireless sensor networks. Their system environment consists of two type of sensors, randomly deployed static sensors and global positioning system equipped moving sensors. These moving anchors travels across the network field and broadcast their current locations on specified intervals. As soon as the sensors which are deployed in random fashion receives three beacon messages (known locations broadcasted by anchors), they computes their locations automatically by using their proposed algorithm.
