I. Introduction
NOWADAYS, Internet users are more interested in consuming the content rather than knowing exactly the location from where it is retrieved. Hence, communication is shifting from a host-centric to a content-centric model, where communication and network traffic volume has been grown exponentially due to huge content demands for real-time and delay-sensitive applications, e.g., multimedia streaming, and broadband services. In this context, Information-Centric Networking (ICN) concept has been introduced as a new promising Internet architecture to solve the existing host-centric Internet's problems of efficiency, scalability, and security [1]. ICN, with the key features of named-based content and in-network caching, has become a “hot” research theme with lots of proposals recently [2], [3].
