Mobile Ad-hoc NETworks (MANETs) consists of a collection of mobile nodes which can move freely. These nodes have characteristic that they can be dynamically self-organized into arbitrary topology networks without a fixed infrastructure. MANETs are highly dynamic network because nodes may join and leave the network at any time. NCPR significantly reduce the routing overhead in the MANET. Once the route is selected from source to destination data is transferred between nodes. This transmission is unsecured. To make it secure a cryptographic technique can be applied.
