Title: Technologies and solutions to dramatically reduce energy consumption in telecom networks

Abstract: Although the ICT contributes significantly to reduce CO2 emission by favoring a less energy consuming behavior of people and enterprises, there are considerable efforts from the telecom industries to dramatically reduce the energy consumptions of their networks and related equipment to something like a half or even more. This is leading to transform the network architecture in order to consolidate the number of nodes and consequently reduce the associated consumptions and the costs and, at the same time, introduce new technologies to increase the network efficiency. This paper review some meaningful use cases to show both such architectural and technological changes. A special focus will be dedicated to the introduction of integrated photonics technologies, particularly CMOS photonics, which will be key enablers of those transformations.

Workshop Program

The workshop will take place on Friday 12 June 2015 in conjunction with IEEE ICC 2015 in London, UK. The program can be found here.


This workshop is sponsored by the following research projects:

  • 5GrEEn (EIT ICT Labs)
  • iCore (European Commission FP7)
  • ProFuN (Swedish Foundation for Strategic Research)

Technical sponsors are:

  • TCGCC - Technical committee on Green Communications and Computing
  • TCCN - IEEE Technical Committee on Cognitive Networks


Reducing world-wide energy consumption and contributing to a more sustainable planet is urgent both from an economical and environmental point of views. With Information and Communication Technologies (ICT) encompassing wireless networks, the Internet of Things (IoT), Cyber Physical Systems (CPS), Wireless Sensor Networks (WSN), Machine-to-Machine Communications (M2M), and cognitive networking, we have the opportunity to detect, prevent, and automate solutions for energy efficiency as well as creating a more sustainable society. Further, energy harvesting ICTs is also expected to play a major role in the near future. However, for this to be a viable option, also the ICT technologies must be energy efficient. Another important aspect with respect to ICTs is the broadband access. It is estimated that 8% of globally generated power will be used by the Access Networks. Thus making broadband access green is a timely topic that should be addressed with high priority. Instead of looking at these three problems in silo, we believe in a venue for researchers and practitioners in these fields to come together and interact. This workshop aims to build this cooperation. Thus we create three different tracks to put together these three areas of interest and enable interactions between them.

Energy Efficiency in ICTs

: According to the GESI study, the ICT sector contributes around two per cent of global greenhouse gas (CHG) emissions. To increase the competitiveness, energy efficiency (E2) must also be a design criterion of the network and service architectures. Flexible networks that adapt their capacity to the requirements and context can lead to significant energy savings. Novel networking paradigms need to be introduced to assure that all components are used with maximum utilization. Green network architectures will be the cross-layer, cognitive and cooperative aggregation of techniques and mechanisms to provide a communication infrastructure where the energy consumption is minimized while guaranteeing the quality/grade of service required by the applications. Along with energy efficiency, spectrum utilization is to be optimized and radiation is to be minimized. Green networking is not only the evolution of legacy networking paradigms but also the revolution of the visionary hybrid networks which is the convergence of the heterogeneous wired, wireless and ad hoc networks.

In this workshop, the following topics of energy efficiency in wireless networks are considered:

  • Energy efficient Internet of Things (IoT), cyber physical systems (CPS), and smart cities
  • Energy efficient wireless/wireline networks
  • Energy efficient ad hoc and sensor networks and their applications
  • Energy efficient algorithms/protocols and their implementations
  • Energy efficient service discovery and service provisioning
  • Energy Harvesting ICTs
  • Cognitive techniques to control networking energy efficiency
  • Optimization of energy efficient networking
  • Physical layer techniques, channel/network coding for energy efficiency
  • Methodologies/architectures for energy efficiency
  • Energy-efficiency measures
  • Energy-efficient flooding/multicasting
  • Collaborative/cooperative/cognitive networking protocols for energy efficiency
  • Algorithms for energy efficient scheduling and resource management
  • Energy harvesting techniques and strategies
  • Cooperative green communications for energy efficiency
  • User mobility modeling to predict and adapt to patterns to reduce energy expenditure
  • Hybrid fiber-wireless networks for energy-efficient delivery of wireless signals
  • Energy Efficiency in 5G Machine-Machine Type Communication Networks

ICTs for Energy Efficiency

: To address the other 98 per cent of the global CHG emissions, ICTs can be used to reduce the energy consumption of industrial/home/office environments/applications. For example, along with the research in low-carbon road transportation technologies, wireless networks can be employed to analyze the traffic jams and help navigators to find a suitable route leading energy savings.

To this extent, in this workshop the topics of wireless networks for energy efficiency consist of:

  • ICT for minimization of the energy consumption of other systems, including transportation, houses, buildings, industrial processes, and smart cities
  • Energy efficient cloud computing, smart grids and emerging applications
  • Sensor networks for energy efficiency in industrial/harsh environments
  • Internet of Things (IoT) for making energy efficient systems
  • Vehicular networks to reduce the CHG emissions
  • ICT systems for a sustainable and green world
  • New designs of equipments/architectures for energy efficiency
  • Energy efficient virtualization of resources
  • Energy efficient radio resource management
  • Energy efficient smart homes and energy monitoring
  • Applications in smart grids and smart and sustainable cities
  • Optimization of smart, homes, cities, societies, and networks

Green Broadband Access

: We are moving towards a networked society with unconstrained access to information and sharing of data available anywhere and anytime to anyone and anything. One of the biggest challenges that the network access segment is facing is how to meet these future requirements and expectations in an affordable and sustainable way. Low energy consumption is the key to achieve this. In fact already today, the operator's energy bill is an increasing part of the operational expenditure, and with the future requirements and expectations there is a clear risk that this may increase even further if nothing is done. There is also a sustainability aspect to consider: even though IT today only contribute to a fraction of a percent of the global CO2 footprint, it is important to maintain or even reduce this in the future.

The goal of this workshop is to provide a holistic understanding of the green aspects of the network access segment as a whole (i.e., mobile plus fixed broadband). This will be achieved by bringing together experts from both academia and industry in the forefront of the energy efficient broadband access field, i.e., energy efficient cellular design, rechargeable energy harvesting wireless networks, energy efficient Passive Optical Network (PON) solutions, and green backhaul/fronthaul strategies specifically tailored for converged wired-wireless scenarios. The range of topics addressed by this workshop is wide, including, but not limited to:

  • Energy efficient MIMO
  • Green massive MIMO
  • Femtocell networks and energy efficiency
  • Multi-tier interference management and energy efficiency
  • Base station energy consumption and optimization
  • Small cell networks
  • Energy and message cooperation
  • Energy harvesting communication network design
  • Transmission policies for energy harvesting nodes
  • Receiver side energy issues
  • Energy harvesting and consumption policies for rechargeable nodes
  • Green backhauling strategies and architectures
  • Green cloud RAN solutions
  • Energy efficient wireless access deployment strategies
  • Standby/idle power management

(Towards Green 5G Mobile Networks). This workshop is supported by the EIT-ICT-Labs 5GrEEn project. The 5GrEEn project coordinator is among the workshop chairs and other lead partners are included in other key positions. The objective is to pinpoint important focus areas and potential solutions when designing an energy efficient 5G mobile network architecture. The workshop will leverage on the partnership with 5GrEEn to build an even stronger technical program.


(Empowering IoT through Cognitive Technologies) addresses two key issues in the context of the Internet of Things (IoT), namely how to abstract the technological heterogeneity that derives from the vast amounts of heterogeneous objects, while enhancing reliability and how to consider the views of different users/stakeholders (owners of objects & communication means) for ensuring proper application provision, business integrity and, therefore, maximize exploitation opportunities. The iCore project manager is one of the general co-chairs of this workshop.


(A Programming Platform for Future Wireless Sensor Networks) has as goal to provide a programming environment where sensor nodes can be programmed as an ensemble rather than individually. This also includes the energy aspects of wireless sensing, sensor networks, and sensor/actuator applications.

The TCGCC chair is also on the steering committee of this workshop.


(IEEE Technical Committee on Cognitive Networks) has as goal to provide a platform for its members in particular, and the cognitive networking research, development, policy making and standardization community in general, to interact and exchange technical ideas to identify major challenges and also drive solutions in the development of cognitive networking technologies. Two of the TCCN vice-chairs are on the committees of this workshop.


This workshop is merger between two successful earlier workshops, namely E2Nets and GBA workshops.


(Energy Efficiency in Wireless Networks & Wireless Networks for Energy Efficiency) workshop has been conducted the past five years in conjunction with IEEE ICC. The previous workshops were well received and we have had good number of papers. The last workshop at IEEE ICC 2014 (Sydney) received 45 papers and we selected 15 papers for oral presentation. The four workshops before also had very interesting sessions spanning over various interconnected topics. We also conducted a general discussion involving all the participants to identify important research issues in the field. Our acceptance rate has been approximately around 35-45% throughout. See for more details.


(Green Broadband Access) has been successfully held twice. The first edition took place at ICC 2013 and the second one took place at Globecom 2014. The ICC 2013 edition was very successful, it received 24 paper submissions, out of which 13 were selected for oral or poster presentation. The workshop had around 20 attendees from both academia and industry. The second edition at Globecom 2014 received 50 papers and accepted 20 for oral or poster presentation.
