Welcome from the General Chairs

Dear colleagues,

As General Co-Chairs of the e-Energy 2011 International Conference on Energy-Efficient Computing and Networking, we are very pleased to welcome you to the second event in cooperation with ACM SIGCOMM at Columbia University in New York City, 31 May - 1 June.After the successful first e-Energy Conference which took place at the University of Passau, Germany, in April 2010, we are certain that this year's event will again offer a stimulating platform for exchange of views and ideas.

The program consists of original academic papers as well as industrial contributions and a poster presentation for work in progress. Energy efficiency has become a major topic of interest, and it is of significant importance both for fundamental research in the area of computer networking and distributed systems and for applied industrial research and development. Power consumption and cooling are, of course, identified as dominating operational cost factors for any IT equipment. While vendors increasingly offer energy efficient hardware, the problem of providing energy efficient software and protocols across different network layers remains largely unsolved, particularly in a distributed systems setting. Also, basic architectural challenges have only begun to be touched upon. Overall, no comprehensive solution is yet in sight, and the many conflicting goals call for comprehensive and in-depth discussions and the possible revision of currently held assumptions and beliefs.

Very many thanks are due to all the people involved in the organization of this event, especially the local arrangements and publicity chairs for their considerable efforts. Many thanks also to the TPC chairs and all those who submitted papers, without whom this event would not have been possible. Finally, of course, we are grateful to you, the attendees!

We hope you will enjoy the conference.

Welcome from the Technical Program Chairs

E-energy 2011 is the second installment of a new conference exploring the intersection of networking and energy efficiency. The first conference took place last year in Passau, Germany.

This year, we received a total of 16 full papers and 12 discussion papers. After a careful review process, each paper received, on average, three reviews. We selected nine regular and four discussion papers for presentation. The authors represent a broad range of countries, with authors from Germany, the USA, Italy, the UK, P.R. China and Turkey contributing 24%, 18%, 11%, 10%, 6% and 6% of the papers, respectively.

The papers illustrate the range of research problems in this field, from characterizing data center energy consumption to motivating general energy efficiency, from low-level video decoding to system level issues, and from backbone efficiency to LTE.

E-energy attempts to bridge the gap between academic research and industrial practice. We invited five industrial talks, organized by Jaafar Elmirghani. In addition, we offer the opportunity for last-minute work-in-progress posters to encourage the exchange of ideas among participants.

We look forward to meeting you in New York!
