A new efficient approach for detecting single and multiple black hole attacks

Abstract

Mobile Ad hoc NETworks (MANET) are networks without infrastructure. The communication range among nodes is limited, where several hops are needed to transmit a packet from the source to the destination. These networks have a constantly changing topology due to its mobile nodes and their arbitrary connections, which make it vulnerable for different attacks. One of the most important attacks in MANET is the black hole attack which degrades the performance of the network by removing all the packets passing through it. There are several techniques for detecting black hole attacks in the ad hoc on demand vector protocol. In this paper, a new approach based on AACK is proposed. The proposed system is to detect the single and multiple black hole attacks by intrusion detection system with SPlitted AACK technique. The system is robust enough to detect all black hole attacks by using an iterative split of the main path until the detection of the malicious nodes. Network simulator 2 is used for simulation. We tested our system on different networks with different network sizes and different numbers of attacks, and we compared our results with some existing intrusion detection system techniques.
