ABSTRACT
The Content-Centric Networking (CCN) architecture, a clean-slate network design, borrows its routing concepts from IP. If content is located on mobile sources, CCN also inherits some of the mobility problems known from IP. In this paper, we explore the design space of CCN mobility solutions by revisiting well-known IP approaches that aim to solve a remarkably similar problem. While mobility solutions may be quite similar in both architectures, we find that a locator/identifier split should be implemented at the network layer in CCN to prevent temporary, topology-dependent information to leak into content that ought to be permanent. Mobility handling further benefits from CCN's security model and multipath forwarding. To provide a starting point for further research, we present a simple mobility approach based on an explicit locator/identifier split.

Mobility support in content centric networks
ICN '12: Proceedings of the second edition of the ICN workshop on Information-centric networkingContent-centric networking (CCN) is designed for efficient dissemination of information. Several architectures are proposed for CCN recently, but mobility issues are not considered sufficiently. We classify traffic types of CCN into real-time and non ...
Seamless Producer Mobility as a Service in Information Centric Networks
ACM-ICN '16: Proceedings of the 3rd ACM Conference on Information-Centric NetworkingIn this paper, we present a service-driven mobility support architecture for Information Centric Networks that provides seamless mobility as an on-demand network service, which can be enabled/disabled based on network capabilities or resource ...
Mobility support for content centric networking
The current Internet architecture was designed more than 30 years ago for a very different set of services than those used today. Several new architectures have been proposed for a Future Internet to better meet today's and future requirements. Content ...
