Abstract

Localization of a node is an important issue in the wireless sensor network as its broad applications in monitoring, emergency rescue operations and battlefield surveillance, etc. Many localization schemes has been used to discover the locations of sensors using beacon nodes, as they are assumed to know their locations through GPS or manual configuration. DV-Hop localization process performs well with the help of beacon nodes that have the ability of self-positioning. But, the localization process is vulnerable to various malicious attacks, one such attack is wormhole, if the network is invaded by a wormhole attack, the attacker tunnels the packets through wormhole link which causes adverse effects on the DV-Hop localization process. Detection of wormhole attack is a particularly challenging, as the adversary does not need to compromise any nodes or have access to any cryptographic keys. In this paper, we analyze the adverse effects of wormhole attack on DV-Hop localization scheme. Simulation results shows secure localization labeling scheme and which detects wormhole attack and prevent its impacts with a high probability.Keywords: Wireless sensor networks, DV-Hop localization, wormhole attack, beacon node, sensor node
