Wireless sensor network has grown to one the most promising fields of research. One primary aspect of WSN is the localization of nodes before any data can be successfully transmitted. Various algorithms have been proposed for the localization of nodes in 2D and in 3D. The 2D localization algorithms work mainly on flat terrains and hence 3D localization algorithms are needed to provide better results in harsh terrain. This paper aims at reviewing different algorithms which are available for 3D localization. Recent works in 3D localization has been covered with the aim to have a better understanding of localization in 3D.
