Detection Mechanism for Jamming Attack in MANET

MANET is a mobile Adhoc network. It is self-configuring network which is infrastructure less in nature. In MANET different nodes are connected through wireless links. Each node is free to move i.e. no central controller is available. There are several types of attacks in MANETs like jamming, selective packet drop attack etc. In this paper we will discuss about jamming attack. A novel technique will be proposed to detect and isolate jamming attack. Experimental results show that proposed technique is more efficient than the existing one.

In this paper a novel technique has been proposed for intrusion detection in MANET, where agents are fired from a node for each node randomly and detect the defective nodes. Detection is based on triangular encryption technique (TE)[9,10], and AODV[1,2,3,8] is taken as routing protocol. The scheme is an 'Agent' based intrusion detection system. This technique is applied on two types of defective nodes namely packet sinking and black hole attack. For simulation purpose we have taken NS2 (2.33) and three type of parameters are considered. These are number of nodes, percentage of node mobility and type of defective nodes. For analysis purpose 20, 30, 30, 40, 50 and 60 nodes are taken with variability. Percentage of defectiveness as 10%, 20%, 30% and 40%.Packet sink and black hole attack are considered as defectiveness of nodes. We have considered generated packets, forward packets, average delay and drop packets as comparisons and performance analysis parameters.

A collection of mobile nodes having ability to organize in a free manner without any fixed infrastructure is known as Mobile Ad hoc Networks (MANETs). Among various types of wireless networks, MANETs are one of the most usable network types. Various routing protocols are there to route the optimal path in an ad hoc network. But because of the wireless nature of MANETs, security of networks is a major issue. It is prone to various types of malicious attacks. Jamming attacks are one of them. These occur by transmitting continuous radio ways to inhibit the transmission among sender and receiver. These attacks effect the network by decreasing the network performance. Previously there had been considerable research in the field of increasing the performance of network by using routing protocols. In our research work we are improving the performance of mobile ad hoc networks under jamming attack by using an integrated approach. The proposed work includes a network with high mobility, usin...

Building an efficient intrusion detection system (IDS) is a challenging task in wireless ad hoc networks due to the resource constraints and lack of a centralized control. In this work, we present a decentralized monitor-based IDS for detecting jamming type denial of service (DoS) attacks at the lower layers of the protocol stack. The varying channel and network dynamics in ad hoc networks can impair service similar to a jamming scenario, resulting in false positives on intrusion detections. To this end, we incorporate a cross-layer design in our IDS to differentiate the malicious jamming behavior from genuine network failures. We validate our design through simulation, and establish the effectiveness of the model. From the simulation results, we observe a significant improvement in the accuracy of detection and lower false positives

The mobile ad-hoc network is more exposed to being attacked, their some fundamental Properties, such as dynamic topology, limited power and limited bandwidth, it is very hard to achieve absolute security in the mobile ad hoc network. Attack avoidance method like encryption and authentication are not enough for reducing the possibilities of attacks. However, these methods are designed to prevent for a set of possible known attacks. These methods are not able to prevent newer attacks that are originated in the existing security measures. So, the mechanism is needed to detect and response for these newer attacks. This paper explores and classifies current techniques of Intrusion Detection System (IDS) on MANET and we have study various intrusion detection techniques in MANET.

In this paper, a jamming attack (a kind of Denial-of-Service attack) was investigated, which interfered with the normal operation of a Mobile Ad Hoc network, which is more vulnerable to various attacks because of its self-configuration, dynamic characteristics, therefore, jammers would affect the network QoS parameters by reducing the throughput and increasing the delay. This problem is solved in this study by enabling the Point Coordination Function, which is a media access mechanism specified by the IEEE standard in some selected MANET nodes (guard nodes) to improve the deficiency of MANET’s performance. The Riverbed modeler was utilized as a simulation tool. In this study, six jammers with two different transmission power values had been applied. In a number of different simulation scenarios with and without jammers, the estimated results showed that the jammers affected the network performance by increasing the delay to 3.0658 sec and decreasing the throughput to 120200.59 bits/...

A mobile ad hoc network is a group of mobile hosts that depends on wireless network interfaces with no use of fixed infrastructure or centralized administration. The main equipments of a mobile station are wireless transmitters/receivers. In this respect, the network can be seen as random chart because of the nodes 'movement. The change of network topology relies on time when nodes move or adjust their transmission and reception parameters. The design of these networks is characterized by its vulnerability to denial of service attacks (DOS).Thus, it is very challenging. In this paper, the focus lies on a special kind of denial of service attacks called Jamming. Indeed, stations in a mobile ad hoc network share a wireless medium. Therefore, a radio signal can be jammed or interfered, which leads to the corruption and loss of the message .In this study , we suggest a new method of detection of that predictable attack by the application of the statistical process control (SPC). The SPC can be the key element of the detection of jamming attack, applied on the packet drop ratio (PDR) which refers as the number of dropped packets to the total of packets sent. The assimilation of this metric shows the nonconforming fraction. As we evaluated the performance, we substantiate that the control chart for fraction nonconforming based on the PDR detects the jamming attack in a real time by a visual graph.

There has been a tremendous growth in the use of wireless communication in the past few decades. Mobile Ad hoc NETwork (MANET) is one of the most important one among various wireless communication mechanisms. In MANET, each node in a network performs as both a transmitter and a receiver. They rely on each other to store and forward packets. Its unique infrastructureless network and self-configuring capability makes it ideal for many mission critical applications, including military use and remote exploration. However, these characteristics also make MANET vulnerable to passive and active attacks due to its open medium, changing topology and lack of centralized monitoring. To address the new security challenges, Intrusion Detection System (IDS) is required to detect the malicious attackers before they can accomplish any significant damages to the network. Many existing IDSs for MANETs are based upon Watchdog mechanism. In this paper, we propose a new IDS called Enhanced Adaptive ACKnowledgement (EAACK) that solves four significant problems of Watchdog mechanism, which are ambiguous collisions, receiver collisions, limited transmission power and false misbehavior report. We use Network Simulator 2 to simulate the proposed mechanism and compare the results with existing mechanisms.

The most important aspect of network is to share the data from one to another. It can either wired or wireless. Both networks provides similar kind of security only. The internet users can have experience of denial of services attack for hacking the data, to avoid the such a hacking provides many techniques to resolve the problem. The jammer is an electronic device used to distrupt the communication. The jammer is made of large number of tiny low power distributed jammer. Use of jammer to avoid the hacking of data. In a network the node setup purpose uses they percolation concept. Based on the network, jammer, performance are evaluated. Finally provides the results in simulation tool such as NS2

The nature of MANETs such as open medium, dynamic mobility and lack of security makes it susceptible to a range of attacks. Jamming attacks is recorded as the highest occurring attacks that exist at physical and MAC layers in MANET. Therefore, an integrated combined layer algorithm (ICLA) is proposed using reverse engineering and anomaly detection technique. The methodology begins by collecting data through OPNET. Analysis and evaluation of the data produces three jammers detection Metrics which are used detect jammers. The performance of the outcome are then tested against other jammers’ model at MAC and physical layer to evaluate the detection performance. This enables identification of jamming attack at both lower layers in MANET. It is combination of three tested metrics such as SNR, BER and throughput that able to detect jamming attack using combined layer approach. The combination of these three metrics across layers shows improvement in identification performance.
