Abstract
Mobile ad-hoc networks(MANET) is the collection of mobile nodes which are self organizing and are connected by wireless links where nodes which are not in the direct range communicate with each other relying on the intermediate nodes. As a result of trusting other nodes in the route, a malicious node can easily compromise the security of the network. A black-hole node is the malicious node which drops the entire packet coming to it and always shows the fresh route to the destination, even if the route to destination doesn't exist. This paper describes a scheme that will detect the intrusion in the network in the presence of black-hole node and its performance is compared with the previous technique. This novel technique helps to increase the network performance by reducing the overhead in the network.
Highlights
Mobile ad-hoc network is formed by the collection of some mobile nodes which can act both as a sender as well as receiver for data communication
Intrusion detection system [2] is used in these networks to detect the misbehaviour in the network
Intrusion detection system acts as a second layer in mobile ad-hoc networks [3]
Summary
Mobile ad-hoc network is formed by the collection of some mobile nodes which can act both as a sender as well as receiver for data communication. They are decentralized networks which are self organizing and self maintaining. As a result of continuously changing topology, there is no fixed boundary of the network. Intrusion detection system acts as a second layer in mobile ad-hoc networks [3]. A scheme is proposed which detects the misbehaving nodes in the network in the presence of black-hole attack [4] [5] and reduces the network overhead.
