A Review Study on Preventing and Detecting Technique of Black Hole Attack in MANET

There are basically two types of black hole attack i.e. internal black hole and External black hole attack. Black hole is a malicious node that wrongly replies for some route requests without having active route to particular destination and drop all the getting packets. If these malicious nodes work jointly as a collection then the damage will be very risky. This type of attack is called cooperative black hole attack. Black hole attack is a type of active attack. Black hole attack can arise when the malicious node on the path attack the data transfer and purposely drop, delay or change the data transfer passing through it. Black hole node treats itself as a trusted node. This is review study on Black hole node send false routing information, claim that it has a best route and cause additional good nodes to route data packets through the black hole node.
