Black Hole Attack Survey Paper

Prevention and Detection of Black Hole Attack in MANET: A Survey
-Mitul Bhatt, Hinaxi Patel, Swati Kariya

Abstract

Mobile Ad-hoc Networks (MANETS) are the networks which are temporary, dynamic, self-configurable and self-maintainable. MANET’s nodes are communicated with each other as being in dynamic topology and without any fix infrastructure. In MANET each and every node acts as a client and server. Any node in the MANET can join and leave the network without any permission. In MANETS have different types of security active attacks like Black Hole, Worm Hole, Grey Hole and Sink Hole Attack which disrupts the network or gaining the data by attacker. Black Hole Attacks are serious security risk to the routing protocol in MANETS. Black Hole Attacks are a kind of attacks where a malicious node advertise itself a shortest path during routing discovery and redirect the data towards malicious node. Malicious node dropped the data or its desired destination instead of original destination. In This Paper focuses of various prevention and detection methods for Black Hole Attack described.
