Mobile Ad hoc NETworks (MANETs) constitutes a group of wireless mobile nodes that transmit information without any centralized control. MANETs are infrastructure-less and are dynamic in nature that is why; they require peremptorily new set of networking approach to put through to provide efficacious and successful end-to-end communication. The wireless and distributed nature of MANET poses a great challenge to system security designers. Although security problems in MANET have attracted much attention in the last few years, most research efforts have been focused on specific security areas, such as establishing trust infrastructure, securing routing protocols, or intrusion detection and response, none of the previous paper proposes security solutions from a system architectural view.
