DETECTION AND REMOVAL OF BLACK HOLE IN MOBILE AD-HOC NETWORK (MANET)
This paper gives information about the detection technique of black hole in the MANET. An ad hoc network is a collection of mobile nodes that dynamically form a temporary network. It operates without the central administration. Hence it becomes more susptable to the attacker .Mostly used on- demand routing protocols used in Ad-Hoc networks is AODV (Ad-Hoc On demand DistanceVector) protocol. The security of the AODV protocol is compromised by a particular of attack called “Black Hole” attack. In this attack, a malicious node advertises itself as having the shortest path to the node whose packets it wants to intercept. To reduce the probability, it is proposed to wait and check the replies from all the neighboring nodes to find a safe route.
