Localization in wireless sensor networks is a main issue, i.e. to determine the position of a given device in the network. Location information of mobile nodes is a demand in many wireless systems. To give the position of the target node reference points have to be used. The node can calculate its distance and/or angle between itself and the reference points. In the 2D space, if a node knows its distance from three reference points its position can also be determined. One more reference point is needed in the 3D space to determine the current position of the target device. In this paper the main localization techniques used in self-organizing sensor networks are described.
