MLDW- A MultiLayered Detection mechanism for Wormhole attack in AODV based MANET

Abstract

Wormhole attack is one of the serious routing attacks amongst all the network layer attacks launched on MANET. Wormhole attack is launched by creation of tunnels and it leads to total disruption of the routing paths on MANET. In this paper, MLDW-a multilayered Intrusion Detection Prevention System approach is proposed to detect and isolate wormhole attack on MANET. The routing protocol used is Adhoc On Demand Distance Vector (AODV). MLDW has a layered framework consisting of link latency estimator, intermediate neighbor node discovery mechanism, packet drop calculator, node energy degrade estimator followed by isolation technique. MLDW effectiveness is evaluated using ns2 network simulator.
