Secure Localization in Wireless Sensor Networks: A Survey

Free registration required

Executive Summary

Secure localization of unknown nodes in a Wireless Sensor Network (WSN) is an important research subject. When WSNs are deployed in hostile environments, many attacks happen, e.g., wormhole, sinkhole and sybil attacks. Two issues about unknown nodes' secure localization need to be considered. First, the attackers may disguise as or attack the unknown and anchor nodes to interfere with localization process. Second, the attackers may forge, modify or replay localization information to make the estimated positions incorrect. Currently, researchers have proposed many techniques, e.g., SeRLoc, HiRLoc and ROPE, to solve the two issues. In this paper the authors describe the common attacks against localization, and survey research state of secure localization.
