Implementation of Black Hole Security Attack using Malicious Node for Enhanced - DSR Routing Protocol of MANET

Abstract

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.

Performance Comparison of Black Hole Attack Detection Mechanism in 6lowpan Over Manet

“…In [3], Rooshabh Kothari et.al were used to implement the DSR technique for route discovery and detection of black hole and worm hole attacks in MANET through the proposed EM-DSR as Enhanced Malicious DSR. In this existing work [4], V.H.La et.al were proposed an mechanism for detection for misbehavior nodes in the light weighted link in the 6LoWPAN Networks.…”

“…A black hole attack [3] [4] is one of the most vulnerable kind of network layer attack where the malicious node under threat obtains the route with finest sequence number and less hop count between the source and destination and subsequently overhears or drops all data packets. The wide usage of MANET and 6LoWPAN [6] in hostile environment and other security perceptive usages have made the security a vital prerequisite for these networks.…”

Modifications of AODV Routing Protocol to Prevent the Effects of Blackhole Attack in MANET

“…Routing [3] is the process of moving information from a source to a destination in an internetwork. During the transfer of information at least one intermediate node within the internetwork is encountered.…”

“…MANETs summarize a new set of demands to be implemented and to provide well organized and better end to end communication. In MANET, there are different types of routing protocols each of them is applied according to the network situation [3].Thus routing protocols are classified into three different categories based on their functionality. V. BLACKHOLE ATTACK IN AODV Blackhole attack is a type of denial of service where a blackhole node can draw all packets sent by the source node by falsely maintaining a fresh route to the destination and then attract without forwarding them to the destination [5].…”

OLSR Fuzzy Cost (OLSR-FC): an extension to OLSR protocol based on fuzzy logic and applied to avoid selfish nodes

“…A difusão em massa do padrão de comunicação IEEE 802.11 fez das redes móveis ad-hoc (MANETs) 1 um dos temas de pesquisa mais promissores [1]. Dentre os assuntos relacionados às MANETs destacam-se os protocolos de roteamento [2], qualidade de serviço [3] e segurança [4]. As principais características dessas redes são: ausência de infraestrutura, capacidade de realizar roteamento multi-salto, mobilidade, 1 Do inglês, Mobile Ad-Hoc Networks (MANETs).…”
