Mobile Adhoc Network is a very powerful, flexible, dynamic, infrastructure less network, in which all the mobile nodes have the right to move around. Every node is recognized as host as well as guest at the same time. There is no central server due to which MANETs are very vulnerable to several kinds of threats. Out of all these attack, one of the most severe attacks is packet drop attack. Packet drop attack may be the consequence of several causes. But most important kind of Daniel of Service attack which is known as Blackhole attack is considered as most serious cause of packet drop. When MANET is suffered from such kind of attack, all of a sudden, network performance is degraded. The efficiency of MANET is totally dependent on co-operation of nodes. If the nodes don't forward the packets to its neighbor, automatically throughput of the network will decrease. This paper includes functionality of Blackhole attack, routing in MANETs with or without Blackhole attack. Finally through simulation it justifies that network performance is degraded in presence Blackhole malicious node.
