Blackhole attack implementation in AODV routing protocol

Mobile Ad-hoc networks are a collection of mobile hosts that communicate with each other without any infrastructure. Because of security vulnerabilities of the routing protocols, wireless ad hoc networks may be unprotected against attacks by the malicious nodes. One of the attacks is the Black Hole Attack against network integrity in this all data packets are absorbed by malicious nodes. Since the data packets do not reach the destination node on account of this attack, data loss will occur. In this paper we see how to implement black hole attack in Ad hoc On demand Distance Vector protocol using network simulator 2.34
