Er.AshuBansal, Er. Dinesh Kumar

An ad hoc network is a collection of mobile nodes that dynamically form a temporary network and are infrastructure less. A black hole is a malicious node that incorrectly replies the route requests that it has a fresh route to destination and then it drops all the receiving packets. So, a black hole attack is one kind of routing disturbing attack, and can bring damage to the network. The damage becomes more serious if group of malicious nodes comes together. This type of attack is known as co-operative black hole attack.Performance of the Black Hole ADOV protocol has been analyzed by varying the number of mobile nodes and black hole nodes. The protocol is analyzed on various performance metrics like packet loss, and throughout of network.
