Research on security of routing protocols against wormhole attack in the ad hoc networks

Ad hoc networks are made of a group of portable terminals with wireless transmitter as multi-hops provisional autonomy system. Ad hoc networks are very easy to be attacked by various kinds of network attacks, as the limited resources, dynamic topology and open communication channel and so on. Wormhole attack is an internal attack means against routing protocols in the Ad hoc networks-CThe research on security of routing protocols against wormhole attack in the Ad hoc networks is performed. The security routing mechanism against wormhole attack in the Ad hoc networks is put forward, on the basis of deeply research on wormhole attack principles and models. The modeling and simulations are presented in detailed.
