The Black Hole Attack Detection and Prevention Techniques in MANET

Abstract

Mobile Ad hoc Network (MANET) is a self-designing network. In MANET mobile nodes are communicated in absence of any central medium/authority. The dynamic topology of MANET allows nodes to connect or leave at any point of the time. From security perspective, it is important that nodes are secure to communicate with each other. There are various attacks that occur in MANET but one of them is a black hole attack. The attacks effect on the reliability, efficiency and working of the network. The node whose packets destructive node wants to block show itself as a shortest path to it. Ad-hoc On-demand Distance Vector routing protocols are used for identification and avoidance of this type of attacks. In this paper, shortly, for the detection and prevention of black hole attack in MANET we will identify some techniques/mechanisms.
