EU FP7 project C2POWER (Cognitive Radio and Cooperative Strategies for Power Saving) main objective is to research, develop and demonstrate energy saving technologies for multi-standard wireless mobile devices, exploiting the combination of cognitive radio and cooperative strategies while still enabling the required performance in terms of data rate and QoS to support active applications. 

As part of the dissemination activities, the project has organized a workshop focused on power optimization techniques, which took place in Lisbon on the 8th of September. The workshop included a keynote speech from Sam Samuel, Executive Director of Bell Labs Alcatel Lucent Ireland (UK) and champion of the GreenTouch Initiative who illustrated the potential for large communication networks efficiency improvements and the consequent reduction of Green House Gases emissions in the ICT sector. Six technical papers on the design of power efficient communication techniques were presented and finally the workshop closed with an interesting panel discussion entitled Power Efficient Wireless Systems: Feasibility and Economic Aspects, animated by Sam Samuel, Prof. Rahim Tafazolli (University of Surrey) and Prof. Sudharman Jayaweera (University of New Mexico, USA).


 
   
 


Call For Papers:

The current and future demands for high speed connectivity, especially for mobile applications constrained by power consumption, drive us to investigate the current state of the art to further advance the technology for improved power efficiency. The truly mobile experience is to have the freedom to roam around anywhere and not be bound to a single location. On the other hand, the energy required to keep mobile devices connected to the network over extended periods of time quickly dissipates. In fact, energy is a critical resource in the design of wireless networks since wireless devices are usually powered by batteries. It is well known that battery life time is one of the top reasons why consumers do not frequently use advanced power hungry multimedia applications on their mobile devices. Battery capacity is finite and the progress of battery technology is very slow, with capacity expected to make little improvement in the near future. It is claimed that battery capacity has only increased by 80% within the last ten years, while the processor performance doubles every 18 months following Moore’s law. In terms of power consumption we have moved from a relatively low 1-2 W range in the first generations to around twice in 3G mobile devices. The perspective for the future does not look encouraging in this aspect, as one could easily expect another doubling in the power demand for 4G devices. From the mobile manufacturer’s perspective the energy consumption problem is critical, not only technically but also taking into account the market expectations from a newly introduced technology.
This workshop looks into the cognitive radio and cooperative techniques for better power efficiency. Cooperative diversity can provide savings in the required transmit power because of the spatial diversity in the system. However, the extra processing and receiving power consumption at the relay and destination nodes for the cooperation gives rise to a trade-off between the gains in the transmit power and the losses in cooperation. Cognitive functionalities on the other hand can be used for context aware transmission schemes for better utilization of the energy.

… In such context, the Workshop will consist of diverse technical tracks:

  • Cognitive radios and networks
  • Cooperative networks and communication
  • Energy efficient communication systems and networks
  • Context awareness and signalling for power saving strategies
  • Short range power efficient communication
  • Cooperative relaying for power saving
  • Energy efficient cognitive handover procedures and policies
  • Energy efficient reconfigurable radios and software defined radios
  • Cooperation in homogeneous and heterogeneous networks
  • Experimental testbeds and results for energy efficient communication techniques
  • Standardization and regulatory aspects and activities for power efficient communication
  • Advanced power saving strategies in Bluetooth, DVB-H, UWB, Wi-Fi, WiMAX, LTE considering network cooperation and using femto-cells.

Invited Speaker:

 

Dr. Sam Samuel, Executive Director of Bell Labs Ireland and UK
 
Sam Samuel is currently Executive Director of Bell Labs Ireland and UK. Prior to this Sam was part of the Regional CTO team for Europe and North based in the UK where he was tasked with the strategizing and positioning of products and solutions to Alcatel-Lucent customers in the region. Previously to this role, Sam was a Technical Manger at Lucent Technologies - Bell Labs Research in the United Kingdom whereSam initiated and directed research on flat cellular architectures and the application of autonomic principles to wireless networks. Before this, Sam was a member of Technical staff at Bell Labs where he was involved in the development of advanced protocols and network architectures for wireless communications systems. Sam's research interests included non-linear dynamics, complexity theory, agent based systems, software architectures and infrastructures, software protocols, advanced wireless systems, mobility and resource management. Sam became a Bell Labs Fellow in 2006 for his work on Flat Cellular Architectures. Before joining the telecommunications industry Sam has served in the Royal Navy from 1981 to 1991 as a Nuclear Reactor specialist. On leaving the Royal Navy he went on to study at Queen Mary and Westfield College, University of London, receiving an MEng in Communication Engineering in 1995 and a PhD in The Application of Non-linear Dynamics to Teletraffic Modelling in 1999.
     
Title:
  Green House Gases, ICT, and the Green Touch Initiative
Abstract:
 
There has been much discussion on the effects of climate change and how certain industrial sectors impact climate change through their carbon footprint.  ICT has been examined in this context and it has been noted that while its current carbon footprint is small, any efficiency gains in this area could potentially impact adjacent industrial areas significantly.  This benefit, however, relies on the assumption that the rate of ICT network efficiency improvements will largely keep pace with traffic growth which has been exponential with the expansion of the Internet. In this talk we review  traffic growth trends and project traffic growth to 2020, apply them  to  recent methods of network energy modelling, and note an increase in network power consumption that is unsustainable.  After applying optimistic energy efficiency improvements associated with well known research directions, we see that this growth can at best be held off for the next decade by such measures.  This brings focus to the need for long term research (10+ years) to unlock larger opportunities for high efficiency networks. The talk then further reviews technological energy efficiency limits in communication networks to provide some perspective on the potential for large efficiency improvements, which brings us to the motivation for the formation of the recently announced GreenTouch Consortium.
