Abstract: Location of a user or a device is of extreme importance. In case of outdoor environments, Global Positioning System (GPS) signal is widely used to determine the position of a user. However, in case of indoor environments, GPS technology fails to carryout. Hence, there is a need to develop an alternative technique for indoor localization. For indoor localization, several techniques are employed, among these techniques, fingerprinting provides several favourable features for indoor environments. This paper carries out the literature survey of fingerprinting techniques used for indoor localization. The fingerprinting is one of the most popular methods of localization because of its high accuracy compare to other methods.
