Prevention and Detection Methods of Black Hole Attacks–A Review

Abstract

A MANET is a continuous self-structured network in which mobile devices are connected wirelessly. The devices in MANET are free to move which pays way for the possibility of attacks. The possibility of attacks includes black hole attacks, grey hole, warm hole, and sinkhole attacks. A black hole referred as "hole of block" refers to an area where the incoming or outgoing packet is silently descended without informing the sender that the data does not reach its receiver and can only be detected by the traffic which is lost. This paper illustrates various prevention and detection methods for black hole attacks.
