A Review on some aspects of Black Hole Attack in MANET

Abstract

A Mobile Ad-Hoc Network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on continual basis. Due to security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Black Hole Attack. The black hole attack is one of the well-known security threats in wireless mobile ad hoc networks. The intruders utilize the loophole to carry out their malicious behaviors because the route discovery process is necessary and inevitable. In this paper we presented a review on few aspects of Black hole attack in MANET's. We have tried to discuss about the reasons why such attacks are seen in mobile ad- hoc networks and performed an analysis on its performance and result on a few of its simulation parameters.
