Where is in a Name? A Survey of Mobility in Information-Centric Networks

Host mobility has been a long standing challenge in the current Internet architecture. Huge proportions of traffic are now attributed to mobile devices [1]; however, despite this promi-nence, mobility often remains a badly handled concept. Some have recently argued that the main reason for this lies in its choice of what to name [2]. The Internet Protocol (IP

Supporting Mobility in a Publish Subscribe Internetwork Architecture

Abstract—Information-Centric Networking (ICN) is constantly gaining momentum within the Future Internet research community. In the PURSUIT research project we are developing a clean-slate Pub/Sub Internetworking (PSI or Ψ) approach with integrated seamless mobility support. The novel ICN mechanisms supported in Ψ, along with smartly placed in-network caches, enable the architecture to handle both mobile and fixed devices in a uniform way. This paper presents a blueprint for optimizing mobility support in Ψ without modifications to the architecture or add-on solutions. We demonstrate a micro-mobility scenario that describes the functionality of Ψ’s core components in supporting mobility and then sketch our plans for future work and a proper assessment of these designs
