WITH THE PROGRESSION OF COMPUTER NETWORKS EXTENDING BOUNDARIES, MOBILE AD HOC NETWORK (MANET)HAS EMERGED AS A NEW FRONTIER OF TECHNOLOGY TO PROVIDE ANYWHERE, ANYTIME COMMUNICATION. DUE TO ITSDEPLOYMENT NATURE, MANETS ARE MORE VULNERABLE TO MALICIOUS ATTACK. THE ABSOLUTE SECURITY IN THE MOBILE ADHOC NETWORK IS VERY HARD TO ACHIEVE BECAUSE OF ITS FUNDAMENTAL CHARACTERISTICS, SUCH AS DYNAMIC TOPOLOGY, OPENMEDIUM, LIMITED POWER AND LIMITED BANDWIDTH. IF THERE ARE NO ATTACKS, THERE IS NO NEED FOR SECURITY. MAJORATTACKS ON MOBILE AD HOC NETWORKS ARE FLOODING, SELECTIVE FORWARDING, SINKHOLE, WORMHOLE ETC. IN A BLACK HOLEATTACK, A MALICIOUS NODE ATTRACTS TRAFFIC TOWARDS IT AND DROPS ALL PACKETS WITHOUT FORWARDING TO THEDESTINATION. THE SECURITY OF THE AODV PROTOCOL IS COMPROMISED BY A PARTICULAR TYPE OF ATTACK CALLED BLACK HOLEATTACK. WE HAVE PRESENTED SEVERAL EXISTING METHODS TO DETECT BLACK HOLE ATTACK IN MOBILE AD HOC NETWORK. INOUR PROPOSED METHOD EVERY NEIGHBOUR NODE MONITORS THE FORWARDING NODE. SO IN A DENSE NETWORK THE DETECTIONRATIO BECOMES HIGH. BECAUSE IN A DENSE NETWORK THERE ARE MANY NODES TO MONITOR THE FORWARDING NODE. OURPROPOSED METHOD CAN EFFECTIVELY DETECT MALICIOUS NODE IN A MOBILE AD HOC NETWORK
