Abstract
Localization technology is crucial in wireless sensor networks (WSN) by forming the basis of various WSN applications. With the advancements of WSN, WSN attacks for node localization have increasingly become an important security issue. The Sybil attack is an example of such attacks where a reputation system is subverted by creating multiple pseudonymous identities. In this paper, a detection and defense algorithm against Sybil attacks based on the distance vector-hop (DV-Hop) method is presented. Experimental results show that the algorithm can effectively improve the security of the node localization in WSN. When the number of beacon nodes is 50, our proposed algorithm reduces the average localization error by 3% than the traditional DV-Hop.
