Detection and prevention of Routing Attacks in MANET using AODV

Abstract

Absence of infrastructure and dynamic nature of MANET invites intruder to launch attack, one of them is flooding. On demand routing such as AODV is more popular then proactive routing use flooding to discover route. Attackers used this concept to launch DoS attack like flooding; black hole and gray hole are the known attack in MANET. In this paper we have proposed a new method based on AODV behavioral metrics t detect and prevent MANET attacks. In this method we have used the RREQ, RREP, PDR, and PMIR as metrics to calculate the QoS of a link and into prediction of attacks. Our proposed scheme will be implementing on NS-3 test bed.
