A Survey of Information-Centric Networking Research
George Xylomenos,Christopher N. Ververidis,Vasilios A. Siris,Nikos Fotiou,Christos Tsilopoulos,Xenofon Vasilakos,Konstantinos V. Katsaros,George C. Polyzos +7 more
TL;DR: A survey of the core functionalities of Information-Centric Networking (ICN) architectures to identify the key weaknesses of ICN proposals and to outline the main unresolved research challenges in this area of networking research.
Journal ArticleDOI
Caching and mobility support in a publish-subscribe internet architecture
TL;DR: An overview of the PSI architecture is provided, explaining its operation from bootstrapping to information delivery, focusing on its support for network layer caching and seamless mobility, which make PSI an excellent platform for ubiquitous information delivery.
Proceedings ArticleDOI
Proactive selective neighbor caching for enhancing mobility support in information-centric networks
TL;DR: Investigations are presented for the steady-state and transient performance of the proposed scheme which identify and quantify its gains compared to proactively caching in all neighbor proxies and to the case where no caching is performed.
Journal ArticleDOI
Enable Advanced QoS-Aware Network Slicing in 5G Networks for Slice-Based Media Use Cases
Qi Wang,Jose M. Alcaraz-Calero,Ruben Ricart-Sanchez,Maria Barros Weiss,Anastasius Gavras,Navid Nikaein,Xenofon Vasilakos,Bernini Giacomo,G Giardina Pietro,Mark Roddy,Michael Healy,Paul Walsh,Thuy Truong,Zdravko Bozakov,Konstantinos Koutsopoulos,Pedro Neves,Cristian Patachia-Sultanoiu,Marius Iordache,Elena Oproiu,Imen Grida Ben Yahia,Ciriaco Angelo,Cosimo Zotti,Giuseppe Celozzi,Donal Morris,Ricardo Figueiredo,Dean Lorenz,Salvatore Spadaro,George Agapiou,Ana Cristina Aleixo,Cipriano Lomba +29 more
TL;DR: This paper presents a novel SliceNet framework, based on advanced and customizable network slicing to address some of the highlighted challenges in migrating eHealth telemedicine services to 5G networks and demonstrates the applicability of the proposed framework in such media-rich use cases.
Book ChapterDOI
On inter-domain name resolution for information-centric networks
Konstantinos V. Katsaros,Nikos Fotiou,Xenofon Vasilakos,Christopher N. Ververidis,Christos Tsilopoulos,George Xylomenos,George C. Polyzos +6 more
TL;DR: This paper study in detail the tradeoff between state/signaling overhead versus routing efficiency for a generic name-resolution system based on a novel DHT scheme with enhanced routing properties, and compare it to DONA, an ICN architecture based on hierarchical resolution and routing.
