Proactive neighbor pushing for enhancing provider mobility support in content-centric networking

CCN (Content-Centric Networking) enables users to retrieve content using the content's name. Researchers face critical challenges in terms of mobility. Since the routing information is part of the content name, when the provider moves, it is necessary to update all the routers' routing information. However, this requires significant costs. In this paper, we propose PNPCCN (Proactive Neighbor Pushing CCN), considering the popularity and rarity of mobility support, for providers in CCN environments. Via simulation studies, we demonstrate that our solutions are effective in terms of shorter numbers of retransmitted Interest packets, and average download times and higher delivery ratios during mobility.
