Abstract
Location information of sensors is crucial in many applications of Wireless Sensor Networks (WSNs). A lot of work has been done for estimating sensors’ location in the network but these approaches are mostly designed without considering security issues which is critical in WSNs. So we should verify the location of sensors to ensure that estimated location is correct. In this paper we propose a novel approach for verifying sensors’ location having minor overhead on the network while not using any additional hardware. This approach is centralized and the verification process is performed in the base station that is much more powerful than sensors and is able to perform more sophisticated tests. Simulation studies verify that this approach is able to detect different attacks and anomalies in sensors’ location.
