Content searching scheme using interesting keyword based overlay network

Content-Centric Network (CCN) sends data to avoid duplicated transmission with content name in the network. However, CCN may cause increase in overhead while maintaining contents management table and create storage problem while storing contents information in the node. In this paper, we proposed a new searching scheme using interesting keyword and manage contents table via overlay network. The content providers with high frequency are chosen in the network. Then an overlay network is constructed using content providers. Via overlay network, it is possible to reduce the number of message transmissions and overhead to manage content management table in the network.
