The Internet Protocol (IP) communication technology used on the Internet has evolved and developed as a versatile communication technology that enables humans to communicate with each other. Nowadays, low-cost sensors, radio frequency identification (RFID), and scalable and high-speed wireless communication technology have made progress and have been applied to the field of “Internet of Things (IoT)” where all kinds of physical objects and things are able to connect to the Internet or the field of “cyberphysical systems” (CPS) which enables interaction between the Internet-connected physical world and cyberspace. IoT and CPS require a system for managing the vast amount of data (i.e. big data) generated by sensors, actuators and other devices, processing such data within the network, and sharing among the interested parties, but a communication model that manages all of the big data on a server or cloud has limits in terms of the communication speed and energy efficiency. Based on a recent white paper from Cisco, there will be 50 billion devices connected to Internet by 2020. Therefore, there is a need for a communication protocol with even higher scalability and real-time capabilities (immediate responsiveness) than the current IP communication. In many IoT systems and CPSs, the main communication will be the sharing of data within a community of objects, such as humans and things. However, the use of traditional IP communication based on a host-centric, end-to-end communication model for communication within a community with numerous objects will lead to an enormous number of communication paths or a significant increase in unnecessary communication traffic, resulting in overall degradation of communication performance and quality. Against such a backdrop, we propose a CommunityORiented IcN (CORIN), a community-oriented communication architecture using the concept of information-centric networking (ICN) which has been studied as a new paradigm for future network technologies. The ICN enables communication centered on information (content) rather than the host-centric communication premised by IP communication. Specifically, information (content) is acquired from a nearby router or node that stores (or caches) the content, through communication using the name of the content, without designating the location (IP address) of a server or the information provider. In CORIN, a “community name” is designated instead of the content name used in ICN to perform communication based on communities. A community used in CORIN is a group of users with common interests in information or content or network-connected users with some kind of
