Enhanced Intrusion Detection for Zombie Exploration Attacks in Mobile Adhoc Networks

Abstract

Wireless networks face different security threat such that there is either a data loss or data inconsistency. Many IDS (Intrusion Detection System) models have been designed to overcome the security threats. We propose an enhanced scheme by which the IDS can act as both an intermediate node as well as a monitoring node preventing DoS (Denial of Service) at its initial stage. The HSQT (Hybrid Sequence Queue Tunneling) technique used minimizes the DoS attack and prevents an attacker node from transferring malicious packet throughout the network. It alerts the source and continues monitoring the misbehavior of the node in its coverage region. For maximum coverage we place more than one IDS node such that almost all the nodes in the scenario are covered by one IDS at least. This improved IDS is a dual purpose concentrating in any node within its coverage and isolating the active connections of the attacker node preventing considerable amount of data loss and false messages in a network.
