Data delivery techniques in content centric routing for IoT: a systematic review

Internet of Things (IoT) connects a number of devices that share data through the internet. Communication between these devices causes a large amount of data in the network that creates a lot of traffic. In order to manage the traffic, the concept of content-centric networking (CCN) is introduced and identified as an effective network model for efficient data delivery in a wireless sensor network. CCN determines routing path based on the content. In this paper, we discuss the CCN architecture and its packet forwarding mechanisms. Also, we provide a review of different techniques of CCN covering naming schemes, architecture and the parameters evaluated and discussed in recent state-of-an-art. This review analysis may help the new researchers to go in-depth in the domain of CCN.
