A Trusted Framework for Discovery of Block Hole Attack Over Unsecured Network
International Journal of Science and Research (IJSR) · 2015
Mobile ad hoc network (MANET) is a self-configuring network of mobile nodes formed anytime and anywhere without the help of a fixed infrastructure or centralized management. It has many potential applications in disaster relief operations, military network, and commercial environments. Due to open,dynamic,infrastructure-less nature, the ad hoc networks are vulnerable to various attacks.AODV is an important on-demand distance vector routing protocol for mobile ad hoc networks. It is more vulnerable to black hole attack. In MANET, black hole is an attack in which a node shows malicious behaviour by claiming false RREP message to the source node and correspondingly malicious node drops all the receiving packets. In this paper, we have reviewed different techniques to prevent black hole attacks in MANET.
