In a world of continuous growth of economies and global population eco-sustainability is of outmost relevance. Especially, mobile broadband networks are facing an exponential growing traffic volume and so the sustainability of these networks comes into focus. The recently completed European funded Seventh Framework Programme (FP7) project EARTH has studied the impact of traffic growth on mobile broadband network energy consumption and carbon footprint, pioneering this field. This chapter summarizes the key insights of EARTH on questions like ”How does the exploding traffic impact the sustainability?”, ”How can energy efficiency be rated and predicted?”, ”What are the key solutions to improve the energy efficiency and how to efficiently integrate such solutions?” The results are representing the foundation of the maturing scientific engineering discipline of Energy Efficient Wireless Access, targeting the standardisation in IETF and 3GPP, strongly influencing academic research trends, and will soon be reflected in products and deployments of the European telecommunications industry.

Maintaining a viable balance between development costs and market coverage has turned out to be a challenging issue when developing mobile software applications. The diversity of devices running third-party developed software applications is rapidly expanding from PC, to mobile, home entertainment systems, and even the automotive industry. With the help of Web technology and the Internet infrastructure, ubiquitous applications have become a reality. Nevertheless, the variety of presentation and interaction modalities still limit the number of targetable devices. In this chapter we present webinos, a multi-device application platform founded on the Future Internet infrastructure. Hereto we describe webinos’ model-based user interface framework as a means to support context-aware adaptiveness for applications that are executed in such ubiquitous computing environments.

4G is a promising solution for the future mobile Internet through integrating heterogeneous radio access technologies (RATs) based on the Internet Protocol (IP) where multi-standard wireless devices allow mobile users to experience ubiquitous connectivity by roaming across different networks and connecting through the RAT that best suits their traffic requirements. However, holding multiple active interfaces incurs significant power consumption to the wireless devices. This necessitates investigating disruptive techniques for decreasing the power consumption of the 4G wireless devices. In this paper, we demonstrate how cognitive radio and cooperative communication can be integrated in 4G networks to conduct wireless devices to either perform vertical handover or execute relaying by exploiting their available short range interfaces (e.g., WiMedia, Bluetooth, etc) to reduce their power consumption while still enabling the required QoS. Simulation and experimental results validate that 4G wireless devices can double their battery lifetime by adopting the proposed strategies.

Sustaining European experimental facilities for Future Internet research is a significant challenge for testbed providers, funding bodies, and customers who depend on their long-term availability. To date, sustainability plans for experimental facilities have been dominated by abstract notions of business value and unclear business models. We argue that this fails to recognise that cost accountability is the critical element necessary to drive efficiency, irrespective of whether revenue is provided from public or commercial sources. Only through cost accountability can facilities make operational management decisions that are aligned with performance metrics and assess the financial viability of business plans. In this paper we demonstrate how cost modelling and usage accounting can be used to support operational and sustainability decisions for a federated cloud experimentation facility.

To determine actual attitudes and practices of those in the Future Internet industry towards user involvement, delegates at the 2012 FIA participated in a focus group and a survey. Continuous user involvement is highly valued and expected to maximise the societal benefits of FI applications. However, just over half of the FI projects apply a user-centred approach, and a large number of survey respondents admitted to being not very knowledgeable about standard user-centred design tools or techniques.

Reducing the network energy waste is one of the key challenges of the Future Internet. Many Internet-based applications require preserving network connectivity for getting incoming remote service requests or confirming their availability and presence to remote peers by sending periodic keep-alive or heart-beating messages. Billions of dollars of electricity is wasted every year to keep idle or unused network hosts fully powered-up only to maintain the network connectivity. This paper describes a new approach to design and implement the cooperative Network Connectivity Proxy () for reducing energy waste in the ever-growing future Internet. The is implemented using Universal Plug and Play (), that uses a set of protocols to allow seamless discovery and interaction between the network hosts and the . The allows all registered network hosts to transition into the low power sleep modes and maintains the network connectivity on their behalf. It handles basic network presence and management protocols like , , etc on behalf of the sleeping network hosts and wakes them up only when their resources are required. Depending on the network hosts time usage model, the can provide about 60 to 70% network energy savings.

The 3DLife EU FP7 Network of Excellence focuses on stimulating joint research and integrating leading European research groups to create a long-term integration of critical mass for innovation of currently fragmented research addressing media Internet. It fosters the creation of sustainable and long-term relationships between existing national research groups and lay the foundations for a Virtual Centre of Excellence in 3D media Internet - EMC. This is a summary of 3DLife’s missions as well as its achievements in the last three years.

CONCORD is the Facilitation and Support action for the EU-funded Future Internet Public-Private Partnerships (FI PPP) programme. CONCORD coordinates FI PPP cross-project activities. It facilitates knowledge transfer and co-creation across projects as well as with related external groups. It focuses on future-oriented strategic planning for FI PPP and on bringing a valuable contribution via unbiased outsider attention to FI PPP structures and processes.

The FLAMINGO project will strongly integrate the research of leading European research groups in the area of network and service management, strengthen the European and worldwide research in this area, and bridge the gap between scientific research and industrial application.

Large-scale computer networks supporting both communication and computation are extensively employed to deal with a variety of existing and emerging demanding applications. These high-performance applications, requiring very high network capacities and specific IT resources, cannot be delivered by the current Best Effort Internet. Optical networking is offering a very high capacity transport with increased dynamicity and flexibility through recent technology advancements including dynamic control planes etc. The European project GEYSERS (Generalised Architecture for Dynamic Infrastructure Services) proposed a novel architecture capable of provisioning “Optical Network and IT resources” for end-to-end service delivery. The proposed approach adopts the Infrastructure as a Service (IaaS) paradigm. The GEYSERS architecture presents an innovative solution to enable infrastructure operators to virtualize their optical network + IT physical resources and offer them as a service based on the user/application requirements. The adoption of Virtual Infrastructures (VIs) facilitates sharing of physical resources among various virtual operators, introducing new business models that suit well the nature and characteristics of the Future Internet and enables new exploitation opportunities for the underlying Physical Infrastructures (PIs).
