PDS- A Profile based Detection Scheme for flooding attack in AODV based MANET

Abstract

One of the main challenges in MANET is to design the robust security solution that can protect MANET from various routing attacks. Flooding attack launched at network layer is a serious routing attack which can consume more resource s like bandwidth, battery power, etc. It is more concealed form of Denial of service attack and resource consumption attack.The route discovery scheme in r eactive routing protocols like Adhoc On Demand Distance Vector(AODV) and Dynamic SourceRouting (DSR) used in MANET makes it more easy for malicious nodes to launch connection request floods by flooding the route request packets (RREQ) on the network. A novel detectiontechnique based on dynamic profile with traffic pattern analysis (PDS) is proposed. Its effectiveness in detecting and ithe malicious node that floods the route request packetsis evaluated using java simulator jist/swans.
