Secure localization and location verification inwireless sensor networks

Sensors´ locations are important to many wireless sensor networks (WSNs). When WSNs are deployed in hostile environments, two issues about sensors´ locations need to be considered. First, the attackers may attack the localization process to make the estimated locations incorrect. Second, since sensor nodes may be compromised, the base station may not trust the locations reported by sensor nodes. Researchers have proposed two techniques, secure localization and location verification, to solve the two issues respectively. In this paper we describe the attacks against localization and location verification, and survey the state of research of both secure localization and location verification.
