Detection of Localization Error in a WSN under Sybil Attack using Advanced DV-Hop Methodology

Abstract

Localization is one of the most important aspects of Wireless Sensor Networks that make it applicable in a number of fields and areas. WSN advances in the technological aspects the number of attacks on the nodes of the WSN have also increased proficiently resulting in a number of security issues. One such attack is the Sybil attack which uses multiple pseudonymous identities to disrupt the reputation of the system. This paper is used to analyse the Sybil attacks using a detection and defence algorithm based on distance vector hop. Simulation of the results using the algorithm will be useful in effectively enhancing security of WSN nodes. In this proposed work based on the experimental analysis we have found out that with 50 beacon nodes, we have been able to decrease the average localisation error buy a solid 4% when compared with previous methodologies.
