SCOM: A Scalable Content Centric Network Architecture with Mobility Support

Abstract

Abstract-Content centric network (CCN) enables users to retrieve contents of interest(e.g. videos, music etc.) using the content names directly. Researchers face two critical challenges in CCN design: content naming and mobility support. The content naming is a fundamental building block for CCN. Users must be able to obtain names of contents of interest fast so that contents can be correctly retrieved. Meanwhile, the rapid development of wireless technologies especially the emergence of cellular 4G networks allows users to retrieve content on the move. However, since mobile users may frequently change their attachment points (e.g. 4G, WiFi, WiMax etc.), the CCN architecture must be able to handle mobility effectively so that a user can still get the content when being connected to a different attachment point. In this paper, we propose SCOM, a scalable content centric network architecture with mobility support, to solve those two issues. SCOM adopts an improved keyword-based naming resolution method to enable faster name retrieval. Users could retrieve names of contents of interest by sending keyword queries to the corresponding Content Resolution Servers (CRS). For mobility, SCOM provides efficient solutions for both keywordbased queries, and content retrievals for users on the move. Via large scale simulation studies using real internet topology, we demonstrated that our solutions are effective in terms of shorter query response times and faster content retrievals during mobility.

Secure producer mobility in information-centric network

“…Among the mobility management protocols proposed for ICN [5,6,18,21,23,24,30,34], Kite [34] is the only one that takes into account security in its design and protects the network against prefix hijacking. Specifically, authors propose to sign traced interests (which corresponds to our Interest Updates) using the producer's private key, in order to handle mobility in a secure fashion.…”

Provider's Mobility Supporting Proactive Neighbor Pushing Scheme in CCN

“…In [10], to solve the issue of detour and synchronization, a location identifier was added to Content Name and an additional server that manages content information was made. When the provider moves, it tells the additional server of this fact and the server transmits the moving information of the provider to the consumer.…”

“…In [32], the architectural ICN scalability is studied from the viewpoint of content naming and user mobility. In this work, the NDN architectural framework is considered.…”
