Abstract: The most important concern for Mobile Ad-Hoc is the Security. Different types of attacks are applied in MANETs open medium, changing its topology dynamically and lack of central monitoring and management, no clear defense mechanism and cooperative algorithms. One of the major security issues in MANET is Black hole attack. Black Hole is one of these attacks, which Attack against network integrity engrossing all data packets in the network and create link break problem. Where the data packets are do not reach the destination node on account of this attack, data loss will occur. In the study many techniques were introduced by researchers to find the attacks in the MANETs. In this paper we have found an approach to remove black hole attack operations using multipath based AODV. The proposed solution is a Multipath AODV routing protocol, which will be able to detect a black hole node in the network. So this problem and defense mechanisms to remove the intruder that carries out the black hole attack using Multi path AODV Scheme. The work describe here is the simulation of black hole attack in the MANET BASED on demand reactive routing scheme. In this Dissertation, an Ad Hoc Network is to be constructed, and analyze the results from the simulation of the existing and proposed by using the NS-2. Keywords: Black Hole Attack, AODV, Multipath AODV, MANET, Performance Matrices.
I. INTRODUCTION Wireless networks can be basically either infrastructure based networks or infrastructure less networks. The infrastructure based networks uses fixed base stations, which are responsible for coordinating communication between the mobile nodes. The ad hoc networks falls under the class of infrastructure less networks, where the mobile nodes communicate with each other without any fixed infrastructure between them. Due to wireless or infrastructure less network security is the biggest issue. Securing is a highly challenging issue for wireless ad hoc networks. Understanding possible form of attacks is always the first step towards developing good security solutions. Security of communication in MANET is important for secure transmission of information. Absence of any central co-ordination mechanism and shared wireless medium makes MANET more vulnerable to attacks there are a number of attacks that affect MANET. Since the functioning of MANET requires cooperation from the participating nodes in the network, security is a primary concern in MANET. Many applications, especially military and emergency rescue, are based on ad hoc networks, where enforcing security requirements are harder than traditional wired networks. Secure routing is also difficult here because of the absence of centralized administration in the network and each node has to trust other nodes for routing their packets. So the presence of any misbehaving nodes in the network can easily disrupt the network operation and damage the communication within the network. Thus, secure routing is one important aspect that has to be incorporated with ad hoc networks for successful commercialization of such networks, and to support secure applications. Hence, providing secure routing through misbehavior detection and mitigation in MANETs is an important and critical research topic. Security is an essential component for mobile ad hoc network. In order to provide security against attacker, researchers are working specifically on the security challenges in MANETs, and many techniques are proposed for secure routing protocols within
