EU FP7 Integrated Project: mobile-cloud-networking.eu

> Integration of— Radio Access Network— Mobile Core Network— Data Centre (computing, storage, applications)

into (decentralized) cloud computing infrastructure (management!)> Advantages: elasticity, costs, performance, e.g., by

exploitation of user location for service provisioning → Follow Me Cloud

STSM Motivation and Results

> Motivation— U Bern with strong experience in Information-Centric Networking

(ICN)— BME with strong experience in energy efficiency of large scale

distributed systems, energy efficient data center design, sustainability issues of the Future Internet, etc.

> Results and Activities— Theoretical analysis of ICN energy saving potential given that ICN

can save network transmissions by caching — Identification of open research issues— Publication at EE-LSDS 2013

Other Issues about Collaboration with BME

> Talks and Visits by Tuan Anh Trinh— Université de Neuchâtel (Peter Kropf)— Talk on Recent Advances in EE of Large-scale Networked

Systems at ETH Zürich (Karin Hummel)> Planned Sabbatical and M.Sc. Lecture by Tuan Anh Trinh at

U Bern in Autumn Semester 2013



14

Conclusions and Outlook

> STSMs have been stimulating research collaboration between U Bern and U Coimbra as well as BME, e.g.,— Joint Ph.D. student supervision— Joint publications— Exchange of researchers, e.g., sabbaticals, and teachers— EU collaboration projects

> COST funding has only covered a small part of collaboration costs.
