Analysis of Black-Hole Attack With Its Mitigation Techniques in Ad-hoc Network

Abstract

In wired and wireless communication, providing security is extremely important. It is a very challenging issue. But the flying evolution in communication technology has triggered to sturdy research interest in wireless networks. The characteristics of wireless networks make this issue even more challenging. In Ad-hoc networks, there is a huddle of autonomous nodes, which dynamically form a temporary multi-hopped, peer-to-peer radio network, without any use of predefined infrastructure. These nodes are generally mobile in nature, and to connect these nodes, the connectionless links are used. These nodes have the potential to self-organize, self-configure, and self-arrangement. Ad-hoc networks do not have fixed structure due to their dynamic nature. Ad-hoc networks are inherently prone to a number of security threats. Lack of fixed infrastructure, use of wireless link for communication, and mobility of nodes make Ad-hoc networks extremely receptive to hostile attacks, blackhole attack being one among them, which can be implemented effortlessly.
