“…Cooperative Black hole means the malicious nodes act in a group. In black hole attack [6] [14], the malicious node waits for the neighbours to initiate a RREQ packet. As the black hole node receives the RREQ packet, it will immediately send a forged RREP packet to the source node advertising itself as having the shortest and optimum route path to the target destination.…”

A Mobile Ad hoc Network (MANET) is a group of movable hosts with wireless network interfaces that structure a temporary network without the support of any permanent infrastructure or central administration. A MANET is also referred as an infrastructure less network because the mobile nodes in the network dynamically locate paths among themselves to transfer packets provisionally. Due to the dynamic network topology in ad hoc network nodes are exchanging plenty of routing packets for creating communication which intern increase network overhead and also increase collision in network. This brings about the matter of security in an ad hoc network. Security is core concern in routing protocol of MANET and affects the performance. In this paper, a innovative request forwarding mechanism is proposed in which source node generates route request packet and broadcast packet to other neighbor nodes to locate destination by implementing black hole attack. Proposed EM-DSR (Enhanced Malicious DSR) is implemented on NS-2 and results shown significant improvement over original DSR in terms of various performance metrics. it has been found that on dense network certain numbers of malicious nodes are supportive to reducing communication overhead and because of density negative effect of malicious attacks which is proposed EM-DSR that is able to reduce. Hence result shows proposed EM-DSR will be helpful to decrease communication overhead.

“…To eliminate the randomness in the result, for each metric, simulation is done for ten different seed values with different random movement of nodes and the average value is taken for the result. Also our approach is compared with two existing approaches Deng's Protocol (Deng and Agarwal, 2002) and ABDSR (Bhalaji and Shanmugam, 2009). The former approach is selected because similar to our approach, it is also an ACK based detection technique.…”

“…The former approach is selected because similar to our approach, it is also an ACK based detection technique. The approach by Bhalaji and Shanmugam (2009) has been selected because it is a recent technique and similar to our approach it does not involve any cryptographic methods for detecting the attack. The metrics used to evaluate the performance are given in the following sections.…”

Black hole attack which is a kind of Denial of Service (DOS) attack is one of the major problems in ad hoc network security. In this paper we propose a solution called Enhanced Dynamic Source Routing (EDSR) Protocol to detect black hole attack. Our technique is an ACKbased detection technique which is capable of finding whether data packets are reaching the destination or not, thus detecting black hole attacks. The experiment results show that our protocol is able to achieve routing security with 16% increase in packet delivery ratio and 31% reduction in packet loss rate when compared to standard DSR under black hole attack. Our technique is light weight because it does not involve high computational complexity and also scalable because it achieves better packet delivery ratio than standard DSR in a network size of 200 nodes.Keywords: black hole attack; DOS attack; DSR routing protocol; wireless ad hoc network.Reference to this paper should be made as follows: Mohanapriya, M. and Krishnamurthi, I.
