Abstract: Wireless Sensor Networks (WSNs) have gained worldwide awareness in recent years. WSN technology becomes popular in all areas of applications along with military, medical, process and electronic industries due to its easy implementation and maintenance. Wireless sensor network (WSN) represents a collection of wireless sensor nodes that coordinate with each other in order to perform a particular task. Localization is the process of finding the position of nodes as data and information are ineffectual if the nodes have no idea of their geographical positions. In this paper, a survey on various aspects or techniques of localization like localization error, parameters of localization, accuracy, bit error probability, energy consumption has been studied.

Keywords: Wireless Sensor Networks, Localization, Multidimensional Scaling.
