چکیده مقاله:
Black hole attack is a well-known attack under which performance and efficiency of mobile ad hoc networks decreases dramatically by malicious nodes. This attack affects functionality of network by dropping data packets. Black hole attack operates based upon two different phases; first, advertising fake routescontaining attacker node. Second, dropping received data packets. When it comes to route advertisement phase, operation of this attack in reactive protocols can be classified into two categories. Advertising fake routes in response to route request (RREQ) packets, and advertising according to route reply(RREP) packets. In related works, Black hole attack has been evaluated and analyzed based on creating fake RREPs inresponse to received RREQ packets. In this paper, however, a novel more destructive attack named Deep Black hole is introduced and evaluated. This attack advertises fake RREPsmore strongly than previous ones. Evaluation of network parameters has been performed related to DSR protocol in NS-2.Simulation results represent that Deep Black hole, compared to ordinary Black hole and selfish nodes, is more damaging andleads to network denial of service. This attack results in a decrease in the number of network routing packets and end-toend delay especially compared to selfish nodes.
