A wireless sensor network (WSN) is a major field of interest and number of sensors are placed in region where data has to be sensed. The sensors are usedto monitor physical or environmental conditions, such astemperature,pressure,in military application, emergency and rescue operation etc. and to cooperatively pass their data through the network to a main verification centre. In this cases the location of a sensor places an important role and this location has to be verified. In order to do the verification we are using two verification method i.e.,on-spot and inregion verification method, which are based on GFT and GFM algorithms. Once the location has verified as trustable, then the sensor and the data it is sensing can be trusted and can be further processed as required by the application.
