Security Architecture for Wormhole Detection and Prevention in IEEE 802.11 WLANs

We propose a FusionMapping for detecting wormhole attacks in wireless multi-hop networks. Wormhole attacks can destabilize or disable wireless networks. In a typical wormhole attack, the attacker receives packets at one point in the network, forwards them through a wired or wireless link with less latency than the network links, and relays them to another point in the network. Initial research focused that this attack is possible on ad-hoc network only, but in present scenario wormhole attack is possible on infrastructurebased wireless LANs also. We propose architecture for wormhole detection and the possibility of wormhole prevention in infrastructure network. The proposed mechanism involves the shared information between communicating access points to prevent rouge access points from camouflaged as false neighbours. The wormholes having higher strength have a higher detection ratio as compared to other method.
