A review: Information-centric networks (ICN) approach for distribution and retrieval abundant content

The necessity of information or content is currently increasing along with the development of mobile technology that is used as a device to access information such as images, sounds, and videos. The demand of communication network services in terms of scalable content distribution, mobility, security, and trusts are also increased. The community has conducted many research activities to solve problems which are related on the wide area network (WAN) or the internet, to develop new architectural models. The model of communication approach in computer networks that emerges is Information-Centric Networks (ICN). It is an approach that perceives information as named content which is independent of its source location and tries to replace it slowly, shifting the host-centric approach that focuses on delivering content by attaching the internet protocol address. This paper aims at providing an overview of ICN function starting from content, routing, caching, security and mobility by reviewing research that proposes ICN architectural models, as well as survey studies that has been conducted by other researchers. In addition, it also discusses ideas about functions of ICN, and this paper is expected to be a trigger for the research community to clarify more about the effectiveness of ICN and what networking infrastructure should be prepared.
