Mobile sensor localization underwormhole attacks: An analysis

Abstract

In many application contexts, the nodes in a sensor network may be required to gather information relevant to their locations. This process of location estimation or localization is a critical aspect for all the location related applications of sensor networks. Localization helps nodes find their absolute position coordinates. Like possibly every system, localization systems are prone to attacks. Through this study we intend to do a low-level identification and analysis of broad, large-scale threat to mobile sensor localization systems due to attacks. In this paper, we study the behaviour of some well-known basic localization schemes under by far the most dangerous attacks on localization called wormhole attacks. The network and attacker model assumed in the paper are chosen so that the analysis unleashes the possibility of a resilient solution to the wormhole attacks problem independent of the nodes not under the effect of attacks.
