CONFERENCE REPORT
20 IEEE Communications Magazine November 2011
The IEEE Communications Society(ComSoc) held its first
fully-virtual,online event from September 26 30,
2011 with numerous of professionalsworldwide participating in 12
separatesessions dedicated to the latest advancesin
energy-efficient communications and green technologies.
Webcast internationally to attendees and then published atIEEE
Xplore, the first annual IEEE Online Conference onGreen
Communications (GreenCom11) was specificallydesigned to address
global warming developments, while pro-moting an ecological
conferencing model that provides time-flexible participation in a
powerful, virtual forum whereenergy efficiency is discussed
energy-efficiently.
Other distinct benefits included the ability of speakers
rep-resenting leading institutions such as Ericsson, Samsung,INRIA,
IMEDA Networks, Create-Net, Telecom ParisTech,
Royal Institute of Technology, Dresden University of
Tech-nology, Tohoku University, Politecnico di Italy and the
Bei-jing Univers ity of Posts and Telecommunications to
offerpresentations live to a truly global audience and then
answerparticipant questions in real-time with the aid of
moderators.This included detailed discussions of wide reaching
global
warming issues ranging from energy-efficient fixed line
andwireless communications to smart grid architecture modelingand
dynamic pricing and response scheduling to energy-effi-cient
solutions for vehicles and the home.
Consisting of a broad spectrum of keynotes and tutorials,IEEE
GreenCom11 commenced on Monday, September 26
with the keynote of Wael Diab, Senior Technical Director,Office
of the CTO at Broadcom Corporation. During his pre-sentation on The
Value of the True Green Data Center,
Wael highlighted multiple power savings strategies for
datacenters that included the consolidation of separate networksand
1Gb links as well as the implementation of
energy-efficientethernets. According to Wael, these improvements
are essentialfor expanding global network performances and features
in acost- and energy-completive framework given that the use of
ITequipment alone creates almost 100 million tons of CO2 a
year.
Immediately following this address, communicationsexperts from
Canada, New Zealand and China combinedonline to explore the newest
advances in home energy man-agement, plug-in electric vehicles
refueled by smart micro-grids and energy-efficient wireless sensor
networks in the nextselected topic presentation. For instance,
representatives fromBeijing outlined their latest research for
reducing daily elec-tricity expenditures by 22.2 percent through
smart meter mon-itoring and two-way communications in addition to
betterutilizing natural resources like wind, power and solar for
pow-ering the transport industry, which represents about 24
per-cent of global greenhouse gas emissions.
On the following day, the online conference renewed witha full
day and night of presentations designed to accommo-date the live
viewing of at least several events no matter theparticipants
country of origin. Among these sessions was thekeynote of Dan
Kilper of Bell Labs, Alcatel Lucent and theChair of the Technical
Committee of the Green Touch Con-sortium, who spoke on
Communication Networks & Sustain-ability. Kilpers address was
dedicated to better monitoringand controlling energy use across
society and in a wirelesstraffic environment that is expected to
increase by 30 percent
a year among businesses alone, while equipment efficiencies
are only growing by 10 to 20 percentannually.
Throughout Tuesday, IEEE Green-
Com11 also offered a collection ofsessions and tutorials
exploring topicslike Toward Energy Efficient Mobile
Communications, Green Wireless Communications andSmart Grid
Communications. During these sessions, leadingindustry
professionals from Spain, Germany, the United King-dom, Finland,
Canada, the United States, Japan and Swedenoffered their expertise
and latest research on specific areasthat included The Minimization
of Power Consumption inBase Stations, Architecture Model Choices
for Smart GridHome Networks, Impact Efficient Power Amplifiers
inWireless Access, and Built-in Renewable Energy Modules;Design,
Implementation and Evaluation.
On the conferences third day, Wednesday, September 28,
IEEE GreenCom11 again provided its global audience with vir-tual
access to five more live sessions including the keynotes ofRaffaele
Bolla, Associate Professor, Department of Communi-cations, Computer
and Systems Science (DIST), University ofGenoa, Italy and Rodney
Tucker, Laureate Professor, Centrefor Energy-Efficient
Telecommunications, Department of Elec-trical and Electronic
Engineering, University of Melbourne,
Australia. With his address titled Enabling Fixed NetworkEnergy
Efficiency Optimization Through Dynamic Adaptation Research
Challenges and European Project Efforts, Bolla high-lighted the
challenges of designing network architectures thatachieve high
levels of energy efficiency through the integrationof enhanced
stand-by capabilities within control frameworks.
As an expert on broadband access technologies and
ener-gy-efficient telecommunications, Tucker continued the
discus-
sion later in the day with his presentation on
GreenCommunications and Cloud Computing. According to him,the
reduction of loss efficiencies and improvement of energyoverheads
is imperative in a world where the Internet, datacenters and cloud
computing infrastructures have alreadycombined to consume three
percent of the worlds electricity.
As a result, there is a necessity for closing the gap betweenthe
theoretical lower bounds of energy switching and its actualenergy
consumption via the use, promotion and implementa-tion of more
efficient applications such as global cloud datastorage and
retrieval services.
Other highpoints included the presentation of three moresessions
exploring green fixed line and wireless communica-tions topics like
Energy-aware Load Balancing for ParallelPacket Processing Engines,
Energy-Efficient Non-coopera-tive Resource Allocation in Multi-Cell
OFDMA Systems,Information and Communication Technologies for
PowerGrid Management and Mode Division Multiplexing forPower
Dissipation in High Spectral Energy System. Green-Com11 then
concluded IEEE ComSocs first-ever, fully virtu-al event with a
final session on Balancing Peer and ServerEnergy Consumption in
Large Peer-to-Peer File DistributionSystems on Friday, September
30.
