ABSTRACT
Mobile Ad hoc Network 'MANET' is a collection of mobile nodes that dynamically form a temporary network without infrastructure. It has many number of applications mainly in the areas of Sensor Networks 'SN', medical, military and rescue operations. Routing is an important component in mobile ad hoc networks and it has several routing protocols, which are affected from different attacks. Ad hoc On demand Distance Vector 'AODV' is one of the most suitable routing protocol for the MANETs and it is more vulnerable to black hole attack by the malicious nodes. A malicious node that incorrectly sends the RREP 'route reply' that it has a latest route with minimum hop count to destination and then it drops all the receiving packets. This is called as black hole attack. In the case of multiple malicious nodes that work together with cooperatively, the effect will be more. This type of attack is known as cooperative black hole attack. In this paper, we have surveyed and compare the existing solutions to black hole attacks on AODV protocol and their drawbacks.
