Climate change is a problem that threatens the world and is caused by the release of greenhouse gas emissions, such as Carbon Dioxide from burning fuels like gas and oil. Our dwellings in the UK consume 30% of the country's total energy demand and so that we can reduce the environmental impact of our lifestyles and create greater energy security by consuming less, the UK Government has laid out a road map of measures that will deliver a zero carbon (or as close as possible) housing stock by 2050, affecting all homes in the UK.A key step on the way to 2050 is the installation of so-called 'smart-meters', which the Government has decided will be rolled out to every house in the UK by 2030. These meters will deliver much greater information to both energy providers and householders. These meters will mean more accurate and transparent billing and should stimulate a more competitive energy market, which would benefit consumers. This greater level of information about how we use energy in and around the home can help us understand where we are wasteful and can tolerate a reduction in consumption and when and where changing our habits and/or lifestyle is not acceptable.What is not understood fully is the relationship between the householder and their preferences and tolerances to change and the sorts of pressures and constraints placed on the energy providers for energy production. Today we enjoy the luxury of having as much energy as we want on demand 24hours a day, but increased reliance on renewable sources, such as wind turbines, combined with a need to reduce our consumption as a nation is likely to mean that more flexible supply and generation systems will become more common and this will have implications for how we use energy in the home. We need to find new ways to help us understand how and where we can reduce our consumption without unacceptable impact on our lifestyles. One way to do this is by understanding how everyday practices in the home (including the use of digital media) result in the consumption of energy and how these practices may change in the future because of societal trends ( e.g. the aging population, remote working, broadband in every home) and then to see how this information can offer opportunities to develop products and services that are attractive to the householder and that have a real impact on energy consumption in the home.The challenges are both technological and sociological and so this research brings together academic experts in the fields of social science, user interface design, product design, building modelling and energy consumption, systems engineering and computer science with householders, energy providers and business to focus on the issue of using digital technology for reducing energy demand in the home. This team contends that in order to develop ways in which householders can reduce their energy consumption significantly, with relatively little effort on their part, the needs of the user must be understood in the wider context of a changing energy landscape and that this can lead to the development of new ideas that can be developed into business opportunities that benefit the UK economy.

The increasing popularity of smartphones and other mobile devices, where the end user has access to a host of rich multimedia functionality, means that the current mobile network architecture is struggling to meet surging data demands. Smartphone ownership in the UK alone has risen from 38% of the population in early 2010 to 60% in 2013 with the ONS reporting that over 32% of adults now access the Internet using their smartphone every day. This figure is expected to grow significantly in the coming years with Cisco predicting that worldwide demand for mobile data traffic will outstrip fixed data, reaching 11.2 Exabytes per month by 2017. Although the global rollout of 4G networks is well underway, it is unlikely that that 4G alone will be able to service the growing data requirements of mobile users. Furthermore, while voice, data, and compressed streaming media are now the norm, it is future social networking applications which will undoubtedly present mobile network designers and operators with their greatest challenge. Both Google and Samsung, through their Glass and Galaxy Gear based concepts respectively, have given us a glimpse of some of the exciting new pervasive technologies that will push the boundaries on the maximum rate at which data can be communicated over mobile networks. For example, using Google Glass, users will no longer just shop and download compressed audio and video, instead they will be immersed into a completely new augmented reality in which they can share their immediate perception and senses with friends and colleagues in the cloud. While this technology will revolutionise social networking it will add further stress to already overburdened mobile networks. To avoid future congestion caused by this huge influx of data, a major change in the way mobile networks are setup and operated is required. However, considerable academic, industrial and regulatory challenges remain and this is the focus of the proposed research programme. To help overcome the future "communications bottleneck" in mobile systems, this project proposes a new paradigm for ultra-high capacity mobile networks by simultaneously and jointly addressing the bandwidth problem and the dynamic network management issues associated with device-to-device communications. Combining the complementary expertise of research teams in Queens University Belfast and Cardiff University, this project will focus on understanding and exploiting incentivised, multimode user equipment operating as an ultra-high capacity underlay network featuring real-time opportunistic adaptive routing all overseen by a context aware mobile network infrastructure.

Rapidly developing digital technologies, together with social and business trends, are providing huge opportunities for innovation in product and service markets, and also in government processes. Technology developments drive socioeconomic and behavioural changes and vice versa, and the rate of change in these makes tracking and responding to high-speed developments a significant challenge in public and private sectors alike. Agile governance and policy-making for emerging technologies is likely to become a key theme in strategic thinking for the public and private sectors. Particular trends that are challenging now, and will increasingly challenge society include developments in technologies on the outskirts of the internet. These include Artificial Intelligence, not just in the cloud but in Edge computing, and in Internet of Things devices and networks. Alongside and in conjunction with this ecosystem, is Distributed Ledger Technology. Together this ensemble of technologies will enable innovations that promote productivity, like peer-to-peer dynamic contracts and other decision processes, with or without human sight or intervention. However, the ensemble's autonomy, proliferation and use in critical applications, makes the potential for hacking and similar attacks very significant, with the likelihood of them growing to become an issue of strategic national importance. To address this challenge, and to preserve the immense economic and productivity benefits that will come from the successful deployment and application of digital technologies 'at the edge', a focused initiative is needed. Ideally, this will use the UK's current platform of experience in the safe and secure application of the Internet of Things. The contributors to this platform include PETRAS partners, and several other centres of excellence around the UK. It is therefore proposed to build an inclusive PETRAS 2 Research Centre with national strategic value, on the established and successful platform of the PETRAS Hub. This will inherit its governance and management models, which have demonstrated the ability to coordinate and convene collaboration across 11 universities and 110 industrial and government User Partners, but will importantly step up its mission and inclusivity through open research calls for new and existing academic partners. PETRAS 2 will maintain an agile and shared research agenda that views social and physical science challenges with equal measure, and covers a broad range of Technology Readiness Levels, particularly those close to market. It will operate as a virtual centre, providing a magnet for collaboration for user partners and a single expert voice for government. User partner engagement is likely to be strong following the successes of the current PETRAS programme, which has raised over £1m in cash contributions from partners during 2018. The new PETRAS 2 'Secure Digital Technologies at the Edge' methodology will inherit the best of PETRAS, including open calls to the UK research community and a partnership-building fund that allows a responsive approach to opportunities that emerge from existing and new user and academic partnerships. PETRAS 2 will be driven by sectoral cybersecurity priorities while retaining a discovery research agenda to horizon-scan and develop understanding of new threats and opportunities. The scope of projects and the associated Innovate UK SDTaP demonstrators, spans early to late TRLs and aims to put knowledge into real user partner practice. Furthermore, the development of many early career researchers through PETRAS 2 research activities should lead to a step change in our national capability and capacity to address this highly dynamic area of socio-technical opportunity and risk.
