RETRACTED ARTICLE: Enhanced trust based encroachment discovery system for Mobile Ad-hoc networks

Abstract

The ultimate goal of this paper is to avoid inclusion of intruder node in the route and to ensure reliability. The trust metrics are used to provide the secure communication. Opportunistic routing scheme is used to ensure reliability or data consistency in the MANET. In the opportunistic routing, each and every node has the chance to select the next intermediate node. The best intermediate node is selected based on the trust value of a node. Each and every mobile node maintains the trust value for its neighbors. The trust value is calculated based on the node’s Quality of Service parameters. In the opportunistic routing, each and every node maintains the trust value for its neighbor nodes. The next forwarder node is selected from the neighbor list. The node with highest trust value is selected as next forwarder node. In the proposed method a node does not maintain the static route to reach the destination. Instead of that the node selects the next forwarder node during runtime. We present a Enhanced Light-weight Trust-based Routing protocol (ELTB). It is light-weight in the sense that the intrusion detection system (IDS) used for estimating the trust that one node has for another, consumes limited computational resource and finding the best optimal path for packet transmission. Moreover, it uses only local information thereby ensuring scalability. Our Enhanced Light-weight IDS takes care of two kinds of attacks, namely, the blackhole attack and the grey hole attack. It is beast suite for highly dynamic environment to handle the frequent link failure. So, the source node transmits the data to the destination node only via trusted node to ensure secure routing in the MANET. The authors have used AODV as the base routing protocol to evaluate our proposed approach and give a performance analysis.
