DoS ATTACKER TRACE BACK FOR MANETS USING CLASSIFIED TRAFFIC MATCHING

Abstract

Denial of Service(DoS) attacks and Distributed DoS attacks constitute a major security threat today. The attackers generally use IP spoofing to conceal their real locations.Several IP Trace back mechanisms have been proposed for the wired Internet.But such mechanisms cannot be applied to the ad-hoc networks,because they rely on assumptions such as trustworthy routers and static route topology that do not hold in the ad hoc platform. In ad-hoc networks, nodes are the devices with limited bandwidth, computational resources, battery power and unpredictable routing topology. Due to this efficient attacker trace back techniques have to be developed for the wireless ad-hoc networks. In this thesis, we develop a new approach, which, can
