Defenses against wormhole attacks in wireless sensor networks

Abstract

Based on analyzing the characteristics of wormhole attacks in the wireless sensor networks, this paper proposes two kinds of defense strategies, which are based on monitoring neighbor node and node location information, in order to achieve effective defense against wormhole attacks using packet encapsulation. We simulate the running state of the static wireless sensor network under normal conditions and under the wormhole attack by using OMNeT++ simulation platform. And the network running process under wormhole attack is simulated in the case of applying the defense strategy based on monitoring neighbor node and the defense strategy based on node location information respectively. By analyzing the specific defense effect, the simulation results highlight the effectiveness of the proposed defense strategy.
