Analysis of Various Malicious Node Detection Techniques: A Review

Priyanka, Mukesh Dalal

Abstract: Mobile Ad-hoc Network (MANET) is self configured network and collection of autonomous nodes that communicate with each other by forming a multi-hop radio network and maintaining connections in decentralized manner. Security is major concern in MANET due to its various features such as open medium, limited power supply and lack of clear lines of defense. It is vulnerable to various types of DoS attacks like black hole, grey hole, worm hole, impersonation etc. In black hole attack, attacker claims to have shortest route to destination by injecting a fake reply message. This document introduces a comparative study of various malicious or DoS nodes detection schemes and analyse their performance based on various parameters viz node mobility, Quality of service, false alarm detection etc.
