Abstract

Detecting and removing black hole attacks are considered to be one major routing security issue in mobile ad hoc networks (MANETs). Malicious nodes existing on the delivery route of packets change a secure route into an insecure route in these networks. Hence, rather than delivering them to the next node, the malicious nodes discard data packets. In this paper, a routing algorithm is proposed based on sending forged packets so as to enhance the accuracy of detecting and removing malicious nodes. According to the proposed method, malicious nodes in a network are detected through sending forged route request (RREQ) and route reply (RREP) routing packets which include the address of unreal destination node. Then, they are removed from routing tables of nodes via sending an RREP message. The method proposed in this paper was able to improve traffic load in the network, identify a short and secure route, detect a number of malicious nodes and optimize the criteria of packet deliver rate, throughput and routing overhead. Simulations results indicated that the percentage of the delivered data packets by the proposed algorithm is higher than that of Intrusion Detection System (IDS) algorithm. Furthermore, thanks to the accuracy improvement in detecting black hole, lack of many conditions for RREQ and RREP and quick routing detection process, the delay in the proposed method was lower than other methods. The above-mentioned factors led to the optimization of throughput.
