A Comprehensive Review of Information-Centric Networking: Concepts, Features, Challenges, and Future Scope

Information-Centric Networking changes the paradigm of the Internet from host-based communication to content-based retrieval. The main ideas of this approach are reviewed in this paper: the basic architectures such as CCN and NDN, naming schemes, and the core concepts comprising name-based routing and in-network caching. Moreover, the content-level security model of ICN is emphasized, while open issues concerning scalability and deployment in real-world scenarios are discussed. In general, the paper summarizes current research trends that shape the move toward more efficient and reliable content-centric networks.
