A hierarchical mobility management scheme for content-centric networking

Abstract

Content-Centric Networking (CCN) has emerged as a promising paradigm in current Internet Due to the interest-driven, we concern more about the content itself rather than the place it located, and therefore, CCN supports subscriber mobility natively, however, it remains a major challenge in publisher mobility. In this paper, we propose a hierarchical mobility management scheme for CCN (HMMCCN) which contains an overlay mapping structure to store the old-to-new name binding relationship and perform the mobility management for mobile nodes. The main goals of this paper are: (a) to propose a mobility scheme suitable for all mobile nodes in CCN, both publishers and subscribers; (b) to describe the hierarchical mobility management procedure during intra-domain and inter-domain handoff; (c) to establish an analytical model and formulate the location update signaling cost.
