W-GREEN 2012 - The fourth International Workshop on Green Wireless (W-GREEN)

The transmitted data volume increases approximately by a factor of 10 every 5 years,
corresponding to an increase of the associated energy consumption by approximately 16 ? 20 %
per year. Currently, 3 % of the world-wide energy is consumed by the ICT sector, contributing to
about 2 % of the world-wide CO2 emissions (comparable to the world-wide CO2 emissions by
airline industry or one quarter of the world-wide CO2 emissions by cars). Doubling of energy
consumptions every 5 years imposes serious concerns for the environment. On the other hand,
10 folds increase in 5 years in data volume does not linearly translate to revenue and the cost of
network operation has now become a critical factor for mobile and wireless networks operations.
Therefore, lowering energy consumption of future wireless radio systems is demanding greater
attention, requires new technologies and solutions, and is becoming an important factor in
specification of future standards, an important differentiating factor in choice of new products.
These needs create inter-disciplinary research challenges including semiconductor technology,
hardware, network architectures and equipments, protocols, services, radio transmission
schemes, network management and deployment/operation. All aiming at higher efficiencies at
transmit power and consumed energy.
The fourth International Workshop on Green Wireless (W-GREEN), is jointly organised by the
Net!Works European Technology Platform (http://www.networks-etp.eu), EU FP7 project
EARTH (www.ict-earth.eu) and GreenTouch consortium (http://www.greentouch.org). The
Workshop will focus on the inter-disciplinary research challenges associated with all aspects of
mobile and wireless networks and systems.
The full day workshop aims to bring together internationally-leading academics and industrial
perspectives, thinking to highlight the key technologies, and solutions and also debate on
appropriate metric for measuring end-to-end system energy efficiency itself and fundamental
limits of energy efficiencies.
Original papers describing both theoretical and experimental results within the scope of Green
Wireless are solicited. Topics of interest include, but are not limited to, the following:
? Holistic view of energy consumption in wireless communications
? Architectures and design of low power equipments (sensors, terminals, network
infrastructure) and energy efficient deployment of HetNets
? Cognitive and opportunistic networks (spectrum sharing models, etc.)
? Cooperative networks
? Reconfigurable networks (geographic routing, admission control, handover, etc.)
? Cross layer and interference pollution (advanced adaptive mechanisms, MAC, scheduling,
power control)
? Traffic engineering
? Network load balance and smart information storage in distributed networks
