A network is a system in which two or more than two computer systems are linked together with wires or without wires. Mobile Ad-Hoc NETworks (MANETs) are autonomous and decentralized networks. MANETs consists of mobile nodes that are free to move in and out of the network. Many routing protocols have been developed for MANETS, i.e. Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR), etc. Due to their dynamic topology, no infrastructure and no central management system MANETs are vulnerable to various security attacks. In this paper, the authors have proposed a scheme to detect black hole attack in a network.
