A Modified Method for Preventing Black-Hole Attack in Mobile Ad Hoc Networks

摘要

Black hole attack is a serious security problem to be solved for active delivery of packets of data in Mobile Ad-Hoc networks. In this problem, a malicious node uses routing protocol to promote itself as having the shortest path to the node whose packets it wants to snatch. In flooding based protocol, if the malicious node reply reaches the requesting node before the reply from the actual node, a fake route is created and try to send the packets of data. This research study deals with the presentation of preventing black hole attack in Mobile Ad Hoc Network (MANET). Various prevention techniques have been discussed in the study that are used to prevent black hole attack. Mobile Ad Hoc networks are susceptible to various attacks, so attacks have to be mitigated in initial setup.
