Localization　is　a　basic　service　and　significant　technology　in　wireless　sensor　networks　(WSNs)　while　in　the　applications　of　WSNs,　security　has　become　an　important　issue.　Secure　localization　has　thus　become　a　serious　issue　due　to　increasing　security　threats　in　wireless　sensor　networks.　In　this　paper,　we　address　the　problem　of　making　sensors　in　WSNs　locate　their　positions　in　an　environment　in　which　there　exists　the　threat　of　wormhole　attacks.　We　propose　a　distance　vector　(DV)-based　robust　localization　(DVRL)　scheme　which　can　fight　against　wormhole　attacks　in　wireless　sensors　networks　without　increasing　hardware　complexity　or　incurring　too　much　computational　cost.　In　DVRL,　sensors　estimate　the　position　relationship　between　each　other　by　the　distance　vector　(DV)　and　ensure　the　security　of　their　localization　by　using　an　effective　detection　mechanism,　which　can　enhance　the　robustness　of　the　localization　method.　Experiment　results　show　that　the　proposed　scheme　is　capable　of　fighting　against　wormhole　attacks　while　improving　accuracy　compared　to　the　basic　DV-Hop　algorithm.　©　2011　Binary　Information　Press　December,　2011.
