Abstract	Mobile ad hoc networks will often be deployed in environments where the nodes of the networks are unattended and have little or no physical protection against tampering. The nodes of mobile ad hoc networks are thus susceptible to compromise. The networks are particularly vulnerable to denial of service (DOS) attacks launched through compromised nodes or intruders. In this paper, we present a new DOS attack and its defense in ad hoc networks. The new DOS attack, called ad hoc flooding attack, can result in denial of service when used against on-demand routing protocols for mobile ad hoc networks, such as AODV, DSR. The intruder broadcasts mass Route Request packets or sends a lot of attacking DATA packets to exhaust the communication bandwidth and node resource so that the valid communication can not be kept. After analyzed ad hoc flooding attack, we develop flooding attack prevention (FAP), a generic defense against the ad hoc flooding attack in mobile ad hoc networks. The FAP is composed of neighbor suppression and path cutoff. When the intruder broadcasts exceeding packets of route request, the immediate neighbors of the intruder observe a high rate of route request and then they lower the corresponding priority according to the rate of incoming queries. Moreover, not serviced low priority queries are eventually discarded. When the intruder sends many attacking DATA packets to the victim node, the node may cut off the path and does not set up a path with the intruder any more. Mobile ad hoc networks can prevent the ad hoc flooding attack by FAP with little overhead.
