A mobile ad-hoc network is collection of mobile nodes which are design to communicate each other without fix infrastructure and central coordination. Since in the MANET, routing protocols have no security mechanism. They are designed only to provide correct routing and have ability to adjust their dynamic changing condition. So MANET is more venerable due to their routing behavior. Routing protocols are more affected by two way, first one is attacks from private node that do not belongs to network and also disrupted by presence of compromise nodes.
