Localization in wireless sensor networks, i.e., knowing the location of sensor nodes, is very important for many applications such as environment monitoring, target tracking, and geographical routing. Since wireless sensor networks may be deployed in hostile environment, sensors' localization is subjected to many malicious attacks. Therefore, sensors' locations are not trustworthy and need to be verified before they can be used by location-based applications. Previous verification schemes either require group-based deployment knowledge of the sensor field, or depend on expensive or dedicated hardware, thus they cannot be used for low-cost sensor networks.
