Comparative Analysis of Black Hole Attack in MANE

MANET is a network, which is very popular due to its unique characteristics from all the other types of networks. Generally, in this type of network the security is missing due to its infrastructure less nature. The node causes cheating during the transmission process in the network Most MANET routing protocols are vulnerable to attacks that can freeze the whole network. Thus these may affects the performance of the network. Black hole attack is one of the possible attacks in MANET. In black hole attack, a malicious node sends the route reply message to the source node in order to advertise itself for having the shortest path to the destination node. The malicious node reply will be received by the requesting node before the reception of the any other node in the network. When this route is created, malicious node receives the data packet, now it's up to the malicious node whether to drop all the data or forward it to the unauthenticated nodes. In this paper, we give an overview of attacks according to the protocols stacks, and to security attributes and mechanisms.
