Caching, security, and mobility in content-centric networking

Existing architecture of the Internet is based on the IP-based model, having the capability to cope with the needs of Internet users. Due to the recent advancements and emerging technologies, need of new architecture has become a research challenge. Content-centric networking (CCN) paradigm is an alternative to IP-based model and is purely based on name-based forwarding and in-network data caching. It is likely to solve certain complications that have not been solved in IP-based protocols. In this chapter, basics of CCN principles with distributed properties of caching, mobility, and secure access control have been discussed and analyzed. Different comparisons are made to examine the strengths and weaknesses of each aforementioned aspect in detail. The final discussion aims to identify the open research challenges and some future trends for CCN deployment on a large scale.
