In recent years mobile Adhoc network features a nice impact on wireless networks. In MANET, each node acts as a router to ascertain a route and transfer information by means that of multiple hops. Manet square measure a lot of susceptible to security problem. Once a node desires to transfer information to a different node, packets square measure transferred through the intermediate no des, thus, searching and establishing a route from a supply node to a destination node is a vital task in MANETs. Routing is an important part in Manet and its many routing protocols. Circumstantial On - demand Distance Vector (AODV) is one in all the foremo st appropriate routing protocol for the MANETs and it's a lot of susceptible to region attack by the malicious nodes. A malicious node that incorrectly sends the RREP (route reply) that it's a modern route with minimum hop count to destination so it drops all the receiving packets this is often referred to as as region attack within the case of multiple malicious nodes that employment in conjunction with cooperatively, the impact are a lot of this sort of attack is known as cooperative region attack. There square measure numerous efforts are created to defend against region attack, but none of the answer appearance most promising to defend against region attack. Thus during this paper, we've got surveyed and compared the present solutions to region attacks o n AODV protocol
