A Research Study On Packet Forwarding Attacks In Mobile Ad-Hoc Networks

Abstract

In this thesis we analyzed selective packet dropping where malicious node drops packets based on packet destinations or some other characteristics ,this type of attacks called packet forwarding attacks. The MANET requires a careful and security-oriented approach for designing communicational protocol .For this we study the DSR and AODV protocols .The information also needed for this is topology information, such as node moving speed , local routing information , such as route cache entries and route updates; and traffic information, all incoming and outgoing traffic statistics, including inter-arrival periods and frequencies. The intuition here is that there should be correlation between node movements and routing table changes, and between routing changes and traffic changes under normal conditions, and that such information can be used to detect anomalies caused by attacks.
