Trust Based Intrusion Detection Systems (IDS) for AODV Routing Protocols over an Ad-Hoc Networks

Abstract

Ad Hoc Networks are very week to attacks due to their dynamically changing topology, lack of
predictable security infrastructures, and vulnerability of nodes, vulnerability of channels and open medium of
communication. To address these concerns this work discusses an ad-hoc Network based intrusion detection system
(IDS) which can make certain security services required by users. The idea is to implement Network based intrusion
detection system (NIDS) for routing in Ad Hoc Networks. As per result, AODV routing protocol with IDS serves
promising. Even in presence of malicious nodes within the network, network performance is not degraded.
Introduction of trust factor, furthermore improves the network performance.
