Abstract
As a promising future network architecture, Named Data Networking (NDN) can provide content consumer mobility support naturally, but the content producer mobility support is remaining a challenging problem. Most previous researches just consider this problem in terrestrial scenarios, which has stable infrastructures to achieve node mobility management. In this paper, we consider it in a Future Space-Terrestrial Integrated Networks (FSTINs) scenario without handover management infrastructure. Specifically, we propose a tracing-based producer mobility management scheme and an addressing-assisted forwarding method via NDN architecture. In order to calculate the route of space segment, we formally describe Multi-Layered Satellite Networks (MLSNs) via a Time Varying Graph (TVG) model and define the foremost path calculating problem, as well as an algorithm that can work in both dense (connected) and sparse (delay/disruption tolerant) scenarios. Performance evaluation results demonstrate that the proposed scheme can support fast handover and efficient forwarding in the FSTIN scenario.
