A Novel Approach for Detection of Single and Collaborative Black Hole Attacks in MANET

Ad hoc On Demand Distance Vector Routing is an extensively accepted routing protocol for Mobile Ad hoc Network. The inadequacy of security considerations in the design of AODV makes it vulnerable to black hole attack in which, malicious nodes attract data packets and drop them instead of forwarding. Among the existing black hole detection schemes, just a few strategies detect both single and collaborative attacks and that too with much routing, storage and computational overhead. In this paper, we propose a novel strategy to detect single and collaborative black hole attacks, with reduced routing and computational overhead. The proposed D-MBH algorithm detects single and multiple black hole nodes using an additional route request with nonexistent target address, computes a threshold ADSN, creates a black hole list and invokes the proposed D-CBH algorithm. Using ADSN, black hole list and next hop information extracted from RREP, the D-CBH algorithm creates a list of collaborative black hole nodes.

A SURVEY ON PREVENTION OF BLACK HOLE ATTACK INMANET

The Mobile Ad Network is a collection of mobile nodes that can communicate with each other via wireless links without using fixed infrastructure or centralized infrastructure. Since there is no centralized infrastructure each node acts as a router as well as hosts. Manets often suffers from security breaches because of its characteristics like dynamic topology, self-configuring node etc. These types of network may be within the network or outside the network.Black hole attack is one of them. Black Hole attack is a type of attack where a node starts behaving selfishly or starts misbehaving in terms of packets. Manets adopt AODV (Ad Hoc on Demand Distance vector) routing protocol. One of the major issues in AODV is Black Hole Attack. The malicious node advertises itself as the shortest path to the destination and the source sends the data to the malicious node and then all the packets are dropped out by the malicious node. This paper provides a comprehensive research on prevention of black hole attack in Manet. A wide variety of literature in this field had been identified and reviewed.

A Cross Layer for Detection and Ignoring Black Hole Attack in MANET

MANET Mobile Ad hoc Network are evolved through various characteristics such as shared media, this property make a routing protocols vulnerable. AODV is a reactive routing where each intermediate node cooperates in the process of route discovery. In this case, the node that behaves as malicious exploit the malfunction of specified service. The black hole attack uses the sequence number that is used to select the freshest route and attract all exchanged data packets to destroy them. Many researchers have dealt with this attack and many solutions have been proposed. These solutions target the network layer only. In this paper, we present our approach to counter black hole attack. This approach is entitled CrossAODV and it is based on verification and validation process. The key point of our approach is the use of the inter layer interaction between networks layer and medium access within the distributed coordination function (DCF) to efficiently detect and isolate malicious nodes. During the route discovery, the verification process uses the RTS / CTS frame that contains information about the requested path. The validation process consists of comparing the routing information with the result of verification phase. Our Approach have been implemented, simulated and compared to two related studies using the well know NS2 Simulator. The obtained results show the efficacy our proposal in term of packet delivery with a neglected additional delay.

Algorithm to Detect and Overcome the Black Hole Attack in MANETs

In Mobile ad-hoc network to resolve security or any other issue, broadcasting is the common factor in networking. MANETs is very new concept and gives us to very different direction to the internet and when we use it, it will become reduce the cost of both the network i.e. with infrastructure and infrastructure less networks. Mobile Ad-hoc network not need backbone infrastructure support and easy to detect in wireless ad-hoc network is very reliable and also contains the routable networking environment in MANETs. In our paper, the effect of black hole attack in AODV based network is studied. The network parameters like Throughput, Packet Delivery Fraction (PDF) and Average End to End Delay are calculated with normal network (without black hole) and a network with one black hole. The performance of network parameters are compared in all the three scenarios. We proposed some scheme is able to finding string of single malicious nodes which drops all the packets.

Detection and Prevention of Gray Hole and Black Hole Attack in MANET

An Ad hoc network is the network with no fixed infrastructure. There is no central administrator so any node can come and move in and outside of the network in a dynamic manner. This makes it more dynamic and complex which makes it more prone to attacks. They can attack either active or passive. Some effects of malicious nodes are Denial of service, Routing table overflow, Impersonation, Energy consumption, Information disclosure etc. A black hole attack node attracts all packets by falsely claiming a fresh route to the destination node and absorbs them without forwarding them to destination. In this work the effect of Black hole and Gray Hole attack on DSR protocol has been considered. Simulation has been performed on the basis of performance parameters and effect has been analyzed using NS2 simulator.Â

A Review on some aspects of Black Hole Attack in MANET

A Mobile Ad-Hoc Network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on continual basis. Due to security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Black Hole Attack. The black hole attack is one of the well-known security threats in wireless mobile ad hoc networks. The intruders utilize the loophole to carry out their malicious behaviors because the route discovery process is necessary and inevitable. In this paper we presented a review on few aspects of Black hole attack in MANET's. We have tried to discuss about the reasons why such attacks are seen in mobile ad- hoc networks and performed an analysis on its performance and result on a few of its simulation parameters.

Various Attacks in MANET and its Counter Measures

In present years, Security is important concern in Mobile ad hoc Network. MANET is self organized network which contains mobile nodes communicate with each other using wireless links. Nodes in the network are free to move in and out of the network. Due to its unique characteristics like Dynamic topology, Lack of central management, Limited resources, they are vulnerable to various types of attacks .In this paper we will present survey of various attacks like Black hole, Gray hole and worm hole attack in MANET. We will also discuss various proposed solutions to prevent and elimination of these attacks.

Simulation and Analysis of AODV and DSR Routing Protocol under Black Hole Attack

In this paper, two routing protocols (AODV and DSR) are simulated under regular operation, single and cooperative black hole attack. This work has been performed by simulator to show consequence of black hole attacks in MANET by using various graphs which are used to collect data in term of several metrics. One common method to perform most of researches in the MANET security field is to simulate and analyze the routing protocols in various scenarios. This work has been based on the implementation and experiments in the OPNET modeler version 14.5. Finally the results have been computed and compared to stumble on which protocol is least affected by these attacks.

Modified DSR protocol for detection and removal of selective black hole attack in MANET

A black hole attack in ad hoc network refers to an attack by malicious nodes, which forcibly acquires the route from a source to destination by falsely advertising shortest hop count to reach the destination node. In this paper, we present a Modified Dynamic Source Routing Protocol (MDSR) to detect and prevent selective black hole attack. Selective black hole attack is a special kind of black hole attack where malicious nodes drop the data packets selectively. We proposed an Intrusion Detection System (IDS) where the IDS nodes are set in promiscuous mode only when required, to detect the abnormal difference in the number of data packets being forwarded by a node. When any anomaly is detected, the nearby IDS node broadcast the block message, informing all nodes on the network to cooperatively isolate the malicious node from the network. The proposed technique employs Glomosim to validate the effectiveness of proposed intrusion detection system.

A Novel Approach for Detecting Black Hole Attack in MANET

The communication in Mobile Adhoc Networks play a vital role in situations like natural calamities or military operations, but due to the dynamic nature of the adhoc networks, it is very important to take care of the security issues, one of the major security issues is the detection of compromised node. The calculation of trust values on the neighboring nodes can significantly solve this problem. This paper presents the calculation of trust values based on the threshold value, if trust value of a node goes beyond the predefined threshold, it is considered to be malicious. The trust value of a node is calculated by taking average of all the trust values for the node. The proposed scheme will be able to detect and isolate the compromised node from the network.

Security is very essential in both wired and wireless network communication. An ad hoc network is a collection of number of wireless computers having dynamically changing topology due to which the security issues are more in case of wireless networks. In this paper the aim is to provide a quantitative analysis of all the security challenges that effect the performance of MANET protocols by analyzing the effects on AODV ( Ad hoc on demand vector routing protocol). The current paper willexplain the concern of black hole, worm holeattacks and presents the impact on AODV routing protocol.

Mitigating Black Hole attack in MANET by Extending Network Knowledge

The Optimized Link State Routing Protocol is developed for Mobile Ad Hoc Network. It operates as a table driven, proactive protocol. The core of the OLSR protocol is the selection of Multipoint Relays (MPRs), used as a flooding mechanism for distributing control traffic messages in the network, and reducing the redundancy in the flooding process. A node in an OLSR network selects its MPR set so that all two hop neighbor are reachable by the minimum number of MPR. However, if an MPR misbehaves during the execution of the protocol, the connectivity of the network is compromised. This paper introduces a new algorithm for the selection of Multipoint Relays (MPR) with additional coverage whose aims is to provide each node to selects alternative paths to reach any destination two hops away. This technique helps avoid the effect of malicious attacks and its easily to implement the corresponding algorithm.

A counter measure to Black hole attack on AODVbased Mobile Ad-Hoc Networks

Security is a major threat and essential requirement for mobile Ad Hoc network. Due to its inherent characteristics, it has many consequent challenges, which needs to be taken care of. In this paper we analyse the black hole attack in MANET using AODV as its routing protocol. Black hole is a type of routing attack where a malicious node impersonates a destination node by sending deceived route reply packet to a source node that initiates a route discovery process. By doing this, the malicious node can deprive the traffic from the source node. We propose a solution that makes a modification in existing AODV routing protocol

Security Enhanced DSR protocol to prevent Black hole attacks in MANETs

The dynamic changing nature of network topology makes any node in MANET to leave and join the network at any point of time. There are many routing protocols that establish the routes between the nodes in the network. The control towards the management of the nodes in the MANET is distributed. This feature does not give assurance towards the security aspects of the network. There are many routing attacks caused due to lack of security. The routing attack addressed in this paper is the black hole attack. The Black hole attack is that where a malicious node advertises itself as it is having the optimal route to the destination. Most of the Routing protocols do not address the issues of the routing attack. This paper describes a solution strategy which will overcome the black hole attacks in MANETs. The proposed solution is that the nodes authenticate each other by issuing security certificate in digital form to all the other nodes in the network. The proposed method is to be adapted on DSR protocol .This method is capable of detecting and removing black hole nodes in the MANET.
