Mobile Ad-hoc NETwork (MANET) is an open loop infrastructure, having independent movement of each node without any decentralized control. Due to dynamic nature. MANET has a many security issues than conventional networks. In this paper Ad-Hoc on Demand Distance Vector (AODV) is used as a routing protocol in MANET. Many types of attack are introduced in MANET such as blackhole attack, wormhole attack,routing table overflow attack, routing cache poisoning attack etc., which occur due to the malicious node and degrade the achievement of AODV. In this paper, blackhole attack is taken into consideration which is more dangerous than other attacks.
