A Novel Method for Intrusion Detection System to Enhance Security in Ad hoc Network

TL;DR

This paper introduces a new intrusion detection system for ad hoc networks that uses local reputation, redemption, and fading mechanisms to improve security and adaptability in highly dynamic environments.

Contribution

It proposes a novel intrusion detection approach based on local reputation with mechanisms for nodes to recover from malicious status, enhancing security in mobile ad hoc networks.

Findings

Simulation results demonstrate improved detection accuracy.

Redemption and Fading mechanisms allow malicious nodes to rejoin.

System adapts to dynamic network topologies.

Abstract

The notion of an ad hoc network is a new paradigm that allows mobile hosts (nodes) to communicate without relying on a predefined infrastructure to keep the network connected. Most nodes are assumed to be mobile and communication is assumed to be wireless. The mobility of nodes in an ad-hoc network means that both the population and the topology of the network are highly dynamic. It is very difficult to design a once-for-all intrusion detection system. A secure protocol should atleast include mechanisms against known attack types. In addition, it should provide a scheme to easily add new security features in the future. The paper includes the detailed description of Proposed Intrusion Detection System based on Local Reputation Scheme. The proposed System also includes concept of Redemption and Fading these are mechanism that allow nodes previously considered malicious to become a part of the network again. The simulation of the proposed system is to be done using NS-2 simulator.
