A Scalable Mobility-Centric Architecture for Named Data Networking

Abstract: Information-centric networking (ICN) proposes to redesign the Internet by replacing its host centric design with an information centric one, by establishing communication at the naming level, with the receiver side acting as the driving force behind content delivery. Such design promises great advantages for the delivery of content to and from mobile hosts. This, however, is at the expense of increased networking overhead, specifically in the case of Named-data Networking (NDN) due to use of flooding for path recovery. In this paper, we propose a mobility centric solution to address the overhead and scalability problems in NDN by introducing a novel forwarding architecture that leverages decentralized server-assisted routing over flooding based strategies. We present an in-depth study of the proposed architecture and provide demonstrative results on its throughput and overhead performance at different levels of mobility proving its scalability and effectiveness, when compared to the current NDN based forwarding strategies.
