Enhanced Detection and Elimination Mechanism from Cooperative Black Hole Threats in MANETs

Malicious node invasion as black hole attack is a burning issue in MANETs. Black hole attacks with a single malicious node is easy to detect and prevent. The collaborative attacks with multiple cooperative malicious node is a challenging issue in security of MANETs as it is difficult to figure out due to its complex and sophisticated mechanism. This study proposed a novel signature-based technique to detect and handle the cooperative black hole attack in MANETs. For this purpose, diverse type of simulation scenarios are used with increasing number of nodes. The parameters such as average throughput, average packet drop, average end to end delay, average processing time and malicious node detection rate are used to measure the impact of signature-based malicious node detection scheme. AODV is used as routing protocol in this study. This study revealed that the performance of MANETs degrades with an increase in a number of malicious nodes. The average throughput of MANETs decreases with increase in average end to end delay and average packet drop. Signature-based malicious nodes detection mechanism is used to counter the cooperative black hole attack. The signature-based technique has enhanced the detection and elimination of cooperative black hole attack in MANETs. This helps in comparatively an increase in average throughput and decrease in packet delay and packet drop.

Ensuring survivability against Black Hole Attacks in MANETS for preserving energy efficiency

Due to its scarce energy sources, and the open nature of transmissions in wireless environments, the wide spread of MANETs is challenged by many factors. Energy efficiency and security issues are considered of the utmost factors, security threats are represented by many attacks, one of which is the vicious Black Hole Attack. In Black Hole Attack, malicious nodes try to engage in as many active connections as possible to jeopardize the scarce network resources. To engage in a connection, during the route discover process, the malicious node sends a prompt route reply message to the source node to acknowledge it has an active route to the destination node, and when it receives the data packets it will simply drop it. Black holes jeopardize the network performance in terms of packet delivery ratio and number of dropped packets.Detecting and neutralizing black hole node is an important task to utilize the network resources efficiently. Network devices spend more than 80% of its available power on communication rather than on processing. Designing an energy-efficient detection scheme is vital to prolong the network lifetime as it reduces the amount of traffic transmitted in the network. The proposed mechanism requires a minimal change to the routing protocol and a minimal overhead to the network. The proposed scheme benefits from the open transmission nature of wireless devices (i.e. minimizing energy consumption) and tries to build a cooperative environment to monitor and observe the behaviour of on-going transmission. In the proposed algorithm, the source node utilizes other nodes in the network (called observer node) to detect if the transmission of data packets to next hop is carried. In case of error, the observer node sends an error message (namely, OERR) to the source node. Upon receiving a repetitive OERR messages, the source node marks the observed intermediate node as a black hole. The performance of the proposed scheme is evaluated using simulation. The obtained results indicate the superiority of the proposed scheme. For example, the proposed algorithm enhances the delivery ratio in dense networks by 45.6% and in by 41% in sparse networks. Moreover, it enhances the dropped packet in dense networks by 75%, and by 63% in sparse networks.

A dynamic threshold based approach for mitigating black-hole attack in MANET

Mobile ad-hoc network is an infrastructure less type of network which does not require any kind of fixed infrastructure. It provides multi-hop communication between the source and destination nodes which are not within the direct range of each other through the intermediate nodes. These intermediate nodes cooperate with other nodes in finding an optimum and shortest route toward the destination. However, in holistic environments, some nodes do not cooperate with other nodes in finding the optimal route towards the destination and intentionally give the false route information of having the shortest path toward the destination with a high destination sequence number in order to attract the traffic toward itself and start dropping of the data packets instead of forwarding it. This type of routing misbehaviour is generally called as black hole attack or full packet dropping attack which is one of the most severe destructive attacks that lead to the network degradation. In this paper, we have proposed a protocol called as Mitigating Black Hole effects through Detection and Prevention (MBDP-AODV) based on a dynamic threshold value of the destination sequence number. In order to validate the efficiency of proposed protocol, the NS-2.35 simulator is used. The simulation results show that proposed protocol performs better as compared with existing one under black hole attack.

Modification in Aodv Protocol for Prevention from Black Hole Attack in Manets

In Wireless ad-hoc network, the infrastructure of MANET's differ to each other due to the topology of MANETs changes time to time because the mobile nodes of MANET's are movable. In MANETs protocols, if any node wants to communicate with another node then they establish a path with the help of adjacent node due to this the security in MANETs protocol is vulnerable. Thus, there are various types of attacks are try to break the security of MANETs protocol. AODV is a popular and most usable protocol of MANET and Black Hole Attack is a severe attack that affects the functionality of AODV protocol. The malicious node treat to the source node which have freshest and nearest path for the destination. In this work, my prime focus specifically is on follow the security against Black Hole Attack. I proposed AODV protocol capture some extra effort for source node and destination node which based on best possible effort (heuristic) with appropriate simulation using ns-2.35.

An Effective CBHDAP Protocol for Black Hole Attack Detection in Manet

Objective: The various features of mobile adhoc networks (MANET’s) are open medium, dynamic topology and absence of centralized monitoring point which introduces various security challenges. One among the security attacks are defined as the black hole attack in this article. Methods: In this paper we introduce a protocol for detecting and avoiding the black hole attacks in MANET’s by an efficient Crypto-key based Black Hole Detection and Avoidance Protocol (CBHDAP). Findings: The suggested protocol generates a group key using Diffie-Hellman (DH) based key agreement black hole detection algorithm then the generated key is forwarded to the authenticated group members. The validation of the nodes in the route from the source to the destination is done before initiating the transmission. The black hole attacks are avoided during transmission by considering the parameters such as time taken for Route Reply (RREP), hop count, Packet Delivery Ratio (PDR) are used. To validate the performance of the proposed approach, it is compared with the existing protocols for the metrics such as detection probability, throughput, end-to-end delay, etc. Improvements: The validation results prove that the CBHDAP provides optimal results for all the metrics like detection probability, throughput, E2E delay etc when compared with the algorithms existed.

Simulation 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. In this paper, we give an algorithmic approach to focus on analysing and improving the security of AODV, which is one of the popular routing protocols for MANET. Our aim is on ensuring the security against Black hole attack. The proposed solution is capable of detecting & removing Black hole node(s) in the MANET at the beginning. Also the objective of this paper is to provide a simulation study that illustrates the effects of Black hole attack on network performance. Previously the works done on MANETs focused mainly on different security threats and attacks such as Impersonation, Wormhole, Jellyfish, and Intrusion detection. Attack of black hole is required on routing protocols AODV, OLSR and TORA. And also check which protocol performs better against black hole attack. There is a need to address all these types of protocols under the attack, as well as the impacts of the attacks on the MANETs. We want to analyse Black Hole attack in MANETs using AODV, OLSR and TORA which are reactive, proactive and hybrid protocol respectively in nature.
