Intrusion Detection and Secure Routing Techniques for Delay and Disorder Tolerant Monitoring Networks

Intrusion detection is the act of detecting unwanted traffic on a network or a device. Monitoring of a node represent a serious threat against routing in delay tolerant network. Delay tolerant Network (DTN) became more popular in the research area recently, because of its application. The mechanism use for the DTN routing is the store-carry and forward approach. Main challenge for the DTN routing is that it discovers the route through the network without an end to end path so nodes in the network connect to the other nodes instantly. This article aim at to incorporate flow correlation information in to the classification process. Compared to contemporary approaches, IDNB (Intrusion Detection using Naive Bayes) demonstrates higher malicious behaviour detection rates in certain circumstances while does not greatly affect the network performances. NB is one of the earliest classification methods applied in intrusion detection system which is an effective probabilistic classifier employing the Bayes’ theorem with naive feature independence assumptions. This paper also review about DTN, types of routing techniques and its issues, some popular routing protocols and their performance in terms of Delay, message Delivery rate, Overhead, Controlling the number of replications of the node. TA could punish compensate the node based on its behaviors. Each node must pay deposit amount before it joins the networks, and the deposit will be paid after then node leave if there is no misbehaviors activity of node. In this paper also focus on security between the nodes in DTN. We introduced a secret key is generated, which is used to share the data. The secret key is automatically changed when the node joins a network and leaves a network based on fast randomized algorithm. So we can increase the level of security in delay tolerant network.
