Abstract: The location verification technique is dense in wireless sensor networks. The nodes called as verifier which is used to verify the location of sensor nodes. In this paper they have assumed that verifiers are secure, also the sensor nodes know their location, and communication range is constant and also signal strength. The sensors initially send their location and its id to all the nodes using flooding and when the verifiers gets the message there takes place collaboration between the verifiers to determine whether the location sent by the sensor node is valid or not based on the results it will decided whether the sensor is valid or malicious. If more number of verifier nodes is used then higher is the probability to detect the malicious node.
