Detection and Prevention of Wormholes Based on Range-Free Localization Scheme

Nnochiri I. U


Mobile ad-hoc networks (MANET) are particularly vulnerable to a severe attack known as the wormhole attack. A few existing protocols detect wormhole attacks but they require special hardware. This research paper aims at developing detection and prevention model against Wormhole attack based on a range free scheme which does not requires an addition costs.The proposed model is easy to deploy: it does not require any especial hardware, like, time synchronization or GPS; nor does it require any complex computation. The performance of this proposed model shows a high detection rate under various scenarios. Proposed model achieves a detection rate about 99.7% versus 99.2% for Secure-AODV model and a detection accuracy rate 98.4% versus 97.1 for Secure-Ad Hoc On demand Distance Vector (AODV).
