Abstract: Malicious node uses protocol loophole launching collusion attack, it badly affects the normal operation of network. Aiming at the system vulnerability of Ad Hoc network, this paper analyses the attack launched by malicious nodes, introduces four kinds of collusion attack solutions, gives their merits and faults. Analysis results show that existing solutions all exist definite defect, they need improve in the aspects of reliability and extendibility.

Key words: Ad Hoc network, collusion attack, wormhole attack
