Abstract

Communication networks, large-scale distributed systems and the (Future) Internet in particular face stern sustainability tests on the increasing energy consumption and CO2 emission of their infrastructures as well as services. According to some recent estimates, the telecommunication sector is responsible for approximately 2% of total CO2 emission, roughly equivalent to the emission of the airplanes as a whole. The energy efficiency issue is crucial not only because of the green/CO2 impacts on the environment but also because it directly hits the wallets of the operators and the users alike (e.g., the cost of operation of wireless and wireline communication systems, energy consumption of data centres, end devices energy consumption, etc.), service providers’ reputation (availability of services, in particular the sensors-based services), and influence the rethinking of energy-aware design methodology of communication systems. This talk addresses some advances on energy efficiency of large-scale distributed systems focusing on our results – in the framework of COST Action 804 - on energy efficiency issues of data centres, embedded systems, energy consumption of Internet based services, energy-performance trade-offs, and last but not least, green issues of future mobile wireless networks (in the framework of the award-winning FP7 IP EARTH project).

Bio

Tuan Anh Trinh received his Ph.D. in Computer Science from the Budapest University of Technology and Economics (BME). He then founded and is the Head of the Network Economics Group at BME. His recent research interests include energy efficiency of large scale distributed systems, energy efficient data centre design, economics-inspired system design, and sustainability issues of the Future Internet. He is involved in the COST Action IC0804 as Co-chair of the working group "Characterization of performance-energy saving trade-off", and in the FP7 IP EARTH project which deals with energy efficiency of future wireless networks as well as other national projects in the field of energy efficient networking and smart grids. He is a co-guest editor of the Special Issue on Energy Efficiency in Large Scale Distributed Systems in Future Generation Computer System journal and the Special Issue on Socio-Economic Aspects of Next Generation Networks in Telecommunications Systems journal. He is a member of the Program Committee of a number of international conferences, including the ACM SIGCOMM E-Energy Conference, IEEE INFOCOM Workshop on Green Networking and Smart Grids. He has been involved in the Program Committee and co-organized the “Economics of Privacy” session in the Future Internet Assembly in Budapest. He has been invited as a visiting scientist at Ericsson Research Budapest (Hungary), British Telecom (UK), Viettel Corporation (Vietnam), Eurecom Institute (France), University of Luxembourg (Luxembourg), among others. He is a professional member of the ACM and an affiliate of the IEEE Computer Society. His Erdős number is 3 (Paul Erdős -> Imre Ruzsa -> Sándor Molnár -> Tuan Anh Trinh; Paul Erdős -> István Joó -> László Györfi -> Tuan Anh Trinh).
