Design and Implementation of Black-hole Attacks in AODV Routing Protocol for Mobile Ad-hoc Networks

Abstract: A black hole attack is a severe attack that can be easily employed against routing in mobile ad-hoc networks. A black hole is a malicious node that falsely replies for any route requests without having active route to specified destination and drops all the receiving packets. If these malicious nodes work together as a group then the damage will be very serious. This type of attack is called cooperative black hole attack. In this paper, we are implementing Black hole attack considering the routing protocol: Ad-hoc On Demand Vector Routing Protocol (AODV) evaluate the network performance metrics like throughput, First route failure lifetime, Packet-Delivery Ratio, Average end-end Delay, Drop rate. The Experiment show that (1) Implementation of AODV for MANET without Black hole attacks (2) AODV for MANET suffers from Co- Operative Black hole attack (3) Comparison of AODV without Black hole attacks and with Black hole attacks in terms of Network Performance Metrics.
