Secure and efficient context data collection using Content-Centric Networking

Context data collection is a fundamental and important process for realizing context-aware recommender or personalization systems. The existing context data collection approaches are based-on traditional TCP/IP that has several disadvantages such as lack of mobility and security. On the other hand, Content-Centric Networking (CCN) provides advantages in terms of mobility, security, and bandwidth efficiency compared to TCP/IP. In this paper, we propose a secure and efficient context data collection and provision approach based on CCN. Simulation results show that this approach can reduce bandwidth consumption by 52.7%–98.9% in comparison to a TCP/IP-based one.
