An　attack-resistant　localization　method　named　ARL　is　proposed　in　order　to　solve　the　security　problems　during　sensor　localization　in　wireless　sensor　networks.　This　method　can　resist　Sybil　attacks　and　wormhole　attacks　effectively　by　using　authentication　and　detection　mechanisms　to　detect　the　legitimacy　of　beacon　nodes　as　well　as　the　reliability　of　positioning　information　and　to　use　credible　information　for　position　calculation.　Experimental　results　show　that　ARL　can　improve　the　accuracy　of　positioning　for　wireless　sensors　in　open,　un-trusted　network　environment.
