A Novel Defence Scheme Against Selfish Node Attack in Manet

In the recent decades the mobile wireless communication becomes more attractive because of its applications in many fields. Moving from the wired communication to wireless communication, the security is the most important property to consider. Specifically in the mobile environment it has the vulnerability, because of its portability and scalability. The mobile ad hoc wireless communication has characteristics such as open medium, distributed environment and changing topology, it makes the network into most vulnerable to the attackers to make the intrusion. The attackers (intruders) can easily enter into the network and compromises the network to behave in the favors of his choice. The Mobile Ad hoc NETwork (MANET) should have the capability to detect such intrusion (attacks) and remove it. To survive the MANET from such intrusion, an Intrusion Detection System (IDS) should be enhanced to the MANET, which can efficiently identify the attacks of the intruders. In this paper it is discussed about various intrusion detection mechanisms and techniques for the MANET to detect the intrusion and intruders.

MANET which means Mobile Ad hoc Networks is popular because it requires no network infrastructure for the mobile nodes within the network to communicate. Any node can join or leave the network independently. The important features of MANET are dynamic topology, self-configuring, peer to peer architecture, use of wireless medium and so on. Due to the dynamic infrastructure, MANET provides high flexibility that attracts them to many application as well as prone to security threats. Many of the vulnerability in MANET are hard to detect. Even though the IDS was used as a security measure in wired network, researchers had explore the IDS as the security solution for the mobile ad hoc network In this paper, we study the different IDS techniques that can be applied on MANET. We will first describe briefly about the different types of security threats and then describe the IDS technique to counter the attacks.

"Since there is no infrastructure in mobile ad hoc networks, each node must rely on other nodes for cooperation in routing and forwarding packets to the destination. Intermediate nodes might agree to forward the packets but actually drop or modify them because they are misbehaving. The simulations in show that only a few misbehaving nodes can degrade the performance of the entire system. There are several proposed techniques and protocols to detect such misbehavior in order to avoid those nodes, and some schemes also propose punishment as well. It is very difficult to design once-for intrusion detection techniques. Instead, an incremental enhancement strategy may be more feasible. A secure protocol should at least include mechanisms against known attack types. In addition, it should provide a scheme to easily add new security features in the future. Due to the importance of MANET routing protocols, we focus on the detection of attacks targeted at MANET routing protocols This includes WatchDog and Pathrater approach. A watchdog identifies the misbehaving nodes by eavesdropping on the transmission of the next hop. A path rater then helps to find the routes that do not contain those nodes. "

With the progression of computer networks extending boundaries, Mobile ad hoc network (MANET) has emerged as a new frontier of technology to provide any where, any time communication. Due to its deployment nature, MANETs are more vulnerable to malicious attack. The absolute security in the mobile ad hoc network is very hard to achieve because of its fundamental characteristics, such as dynamic topology, open medium, limited power and limited bandwidth. The Prevention methods like authentication and cryptography techniques alone are not able to provide the security to these types of networks. Therefore, efficient intrusion detection must be deployed to facilitate the identification and isolation of attacks. In this paper we have surveyed various intrusion detection techniques in MANET and analyzed their fruitfulness.

Wireless sensor network is a set of distributed sensor nodes. Which are randomly deployed in geographical area to capture climatic changes like temperature, humidity and pressure. In Wireless Network MANET is a Mobile Ad-Hoc Networks which is a one self-configurable network. MANET is a collection of Wireless mobile node which is dynamically moves from one location to another location. Both attacks Active as well as Passive attacks is in MANET. It doesn’t have a static structure. Security for wireless network is much difficult as compare to wired networks. In last few years many security and attacks issue are face many researchers in MANET. Attacks like Packet dropping attack, Black-Hole attack, Denial of Service attack, wormhole attacks and Packet modification attacks found in MANET. At the time of data communication all the above mentioned attacks access data easily without permission. To solve the problem of attacks in MANET and secure data communication use Intrusion Detection Sy...

Mobile Ad hoc Network consists of some nodes that are stand randomly in operational environment. Because nodes are without any predefined infrastructure and mobility then that are susceptible for intrusion and attack. Securing is an important field in this type of network. In this paper we aim to representing concept of intrusion detection and then survey some of major intrusion detection approach in MANET and aim to comparing in some important field such as: use methods, type of attacks addressed, overhead, and architecture.

The MANETs is one type of Ad Hoc network that is used for mobile communication. The Mobile Ad Hoc NETworks (MANETS) are used when the user is moving. Because MANET does not depend on fixed infrastructure. In MANETs Wireless networks are used to connect with different networks. surrounded by all the contemporary wireless networks, Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. The self-configuring ability of nodes in MANET absolutes it admired among essential mission applications like military use or emergency recovery. The mobility and scalability carried by wireless network ended it possible in many applications. Surrounded by all the contemporary wireless networks Mobile Ad hoc NETwork (MANET) is one of the most significant and exclusive applications. In this review paper a qualified learns of Secure Intrusion-Detection Systems for determining malicious nodes and attacks on MANETs are presented. One of the main advantages of wireless networks i...

Ad Hoc Network due to its infrastructure less ability. It has been providing lots of benefits in the field of communication and has changed the word into Global village. It has many features for example deployment facility, limited resources, dynamic topology and physical insecurity, the chances of attack increased than any other network. And due to dynamic topology, no static solution is applicable. There are two defense mechanism that can reduce the attack. First includes cryptography etc. If this defense is broken then intrusion detection system helps to reduce the attack ratio. In this survey paper, intrusion detection system taxonomy has been observed through different point of view. But the IDS detection mechanism has been elaborated in detail. And a comparison has been performed between the detection mechanism been used so far. Finally, we concluded useful information related to different mechanism and which mechanism has been used the most and performed well.
