Course Description

Is it true that the Internet consumes more than 3% of all energy in World?
Does a search on the Internet consume the same amount of energy as preparing a cup of coffee?
How can we allow the Internet to grow without depleting the World's energy resources?

This new course aims to provide answers to the above questions with emphasis on describing how to analyze energy consumption of networks, devices and servers while identifying the best strategies to reduce the overall environmental impact of the Internet. 

The course will provide an up-to-date review of the main issues in energy saving in today and in tomorrow's Internet. Presentation of the different subjects will be based on analytical models, simulation analysis and actual measurements, and enable the attendees to gain both theoretical and practical insights to the design of energy efficient networking solutions.

Current case studies will be presented that include:
- energy consumption breakdown of a typical cellular network provider
- energy consumption breakdown of a typical data center
- actual measurements on energy consumption from a real Wi-Fi testbed
- application of green paradigm to the design of next generation radio networks

Who Should Attend

Intermediate level of instruction.

This course is intended for communications engineers working on networks and service design and dimensioning.


NEW!  Designing the Green Internet

Fabrizio Granelli

Ph.D., Associate Professor

Fabrizio Granelli is Associate Professor and Delegate for Education at the Dept. of Information Engineering and Computer Science (DISI) of the University of Trento (Italy).
He received the «Laurea» (M.Sc.) degree in Electronic Engineering from the University of Genoa, Italy, in 1997, with a thesis on video coding, awarded with the TELECOM Italy prize, and the Ph.D. in Telecommunications from the same university, in 2001. Since 2000 he is carrying on his research and didactical activities (currently Associate Professor in Telecommunications) at the Dept. of Information Engineering and Computer Science – University of Trento (Italy) and coordinator of the Networking Laboratory. Between 2004 and 2015 for a total of six months, he was visiting professor at the State University of Campinas (Brasil). In 2016, he was visiting professor at the University of Tokyo (Japan).  He was IEEE ComSoc Distinguished Lecturer for the period 2012-15 (2 terms).

He is author or co-author of more than 170 papers published in international journals, books and conferences, focused on networking, with particular reference to network performance modeling, cross-layering, wireless networks, cognitive radios and networks, green networking and smart grid communications.

Prof. Granelli is guest-editor of ACM Journal on Mobile Networks and Applications, special issues on “WLAN Optimization at the MAC and Network Levels” and “Ultra-Wide Band for Sensor Networks”, and Co-Chair of 10th and 13th IEEE Workshop on Computer-Aided Modeling, Analysis, and Design of Communication Links and Networks (CAMAD’04). Dr. Granelli is General Vice-Chair of the First International Conference on Wireless Internet (WICON’05) and General Chair of the 11th, 15th and 18th IEEE Workshop on Computer-Aided Modeling, Analysis, and Design of Communication Links and Networks (IEEE CAMAD ’06 - ’10 - ’13). He is TPC Co-Chair of GLOBECOM 2007-2009 and 2012 Symposia on “Communications QoS, Reliability and Performance Modeling” an TPC Co-Chair of GLOBECOM 2014 Symposium on “Selected Areas in Communications – Green Communications Track”.
Prof. Granelli is the Chair of the IEEE Standardization Research Group on “Software Defined and Virtualized Wireless Access”. He was voting member and contributor of IEEE SCC41 for standards IEEE P1900.1 and IEEE P1900.2.
He was officer (Secretary 2005-2006, Vice-Chair 2007-2008, Chair 2009-2010) of the IEEE ComSoc Technical Committee on Communication Systems Integration and Modeling (CSIM) and he is currently Secretary of IEEE ComSoc TC on Transmission, Access and Optical Systems.

He is Senior Member of IEEE and Associate Editor of IEEE Communications Surveys and Tutorials, IEEE JSAC Green Communications and Networks Series and International Journal on Communication Systems.
