Content-centric internetworking for resource-constrained devices in the Internet of Things

Content-Centric Networking (CCN) is a newly proposed networking architecture for the future Internet. It has superiorities over today´s IP-based architecture in some aspects. On the other hand, the Internet of Things (IoT) is a direction of the future Internet. Due to the existence of large amounts of weak network devices (NDs) with constrained resources, current CCN models that are designed mainly oriented to Super Routers (SRs) in the core networks are not appropriate for the edge networks in IoT. In this paper, we propose an internetworking scheme for weak NDs based on task mapping. In this scheme, weak NDs with constrained resources map the overcapacity tasks (in terms of storing, publishing, and retrieving) to SRs. Then, based on this scheme, we present two specific strategies for NDs as producers and consumers, respectively. Finally, we take cameras as typical NDs to illustrate the process of the communication by using our proposed scheme.
