۱ | INTRODUCTION

The Internet of things (IoT) is a paradigm where all billions of devices communicate at the same time with each other and the humans over the Internet to implement some predefined objectives. These devices can be equipped with identifying, sensing, actuation, and processing capabilities, ranging from resource‐constrained to the powerful devices.1-3 Contrary to traditional networks, IoT is a challenging environment, mainly due to resource‐constrained devices, heterogeneous access technologies, and special traffic patterns (eg, unique, heavy, and transient data). Some evolutionary approaches and standardization activities are pursued to provide IP‐based networking functionalities for IoT (eg, 6LoWPAN, RoLL, and CoRE).4 Although, these efforts have been illustrated through their valuable achievements, they still face great challenges. It is still very difficult to simultaneously service the large number of processing under the stringent requirements of IoT, complex mobility, and multicast in the case of large‐scale deployment. As the number of connected devices is growing rapidly and becoming ubiquitous, there is the need to provide a connectivity model for IoT environment to support more efficient and large‐scale deployment for its applications. Hence, the research community is considering a novel communication model called content‐centric networking (CCN) as a fully promising solution in the future. This network uses application data names directly to achieve the information retrieval by using named data instead of host to host in the Internet’s current conversation model, in which named content is uniquely identified and independently retrieved from its location.5 Interest packets (IntPk) and data packets (DataPk) are 2 types of packets that identify the content. Once a CCN node receives an IntPk message, the DataPk will be sent back to the consumers to ascertain if an appropriate content is found; otherwise, the IntPk is forwarded to upstream towards other potential content sources. In this CCN scheme, some key features have been explored to take several advantages in IoT domain like uniquely identified, retrieved independently from its location, and content‐based security. In parallel, the fact that IoT is increasingly focusing on data and information rather than point‐to‐point communications may lead to the adoption of CCN architectures and principles. As a result, CCN helps to improve energy efficiency, reduce bottleneck link, retrieval delay time, and limit massive access to resource‐constrained devices, which is a clear indicator to prove the prospects of the CCN‐IoT integration onwards.6,7 However, this integration is still at its infancy, and therefore, there exist numerous challenges that need to be addressed concerning naming, security, discovery and delivery, and an especially caching aspect that will be intensely investigated in this paper.
