英文摘要：

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.
