Renowned experts in Electronics and Computer Science from the University of Southampton have outlined the disruptive potential of the emerging Internet of Things (IoT) as part of The Royal Society’s Transforming our Future conference series. Professor Dame Wendy Hall and Professor Bashir Al-Hashimi addressed an audience of industry leaders, policymakers and academics at the influential Internet of Things: Opportunities and Threats event in London on Tuesday, 3 October.

The conference, part of a series exploring the next decade’s major scientific and technical challenges, highlighted the huge growth of interest in IoT technology with its wealth of emerging applications while underlining its potential to increase productivity and change lifestyles.

Speakers at Tuesday’s event outlined key issues that pose a challenge to the translation and adoption of IoT technology, including security, economic, ethical and legal matters.

Dame Wendy, a Regius Professor in Computer Science and Director of the Web Science Institute, says, “I was thrilled to be asked by The Royal Society to organise this discussion meeting on the IoT. It is very timely as IoT devices begin to hit the high streets and are increasingly utilised by industry. It is clear that there are both opportunities and threats from this emergent technology but teasing out how we make the most of the opportunities whilst mitigating the threats is incredibly complex.”

She adds, “We addressed this issue from the perspective of four different panels and a very diverse set of panellists drawn from both industry and academia. The result was a set of very lively discussions which will be summarised in a report that we hope will have a significant impact in this space.”

Dame Wendy chaired the conference’s Technology session, which included a presentation and panel discussion with Southampton’s Dean of Physical Sciences and Engineering Arm Professor Bashir Al-Hashimi. His talk covered recent developments in hardware and energy management software that underpin the realisation of the vision of self-powered IoT devices.

Bashir explains, “The advances from work carried out with colleagues at Arm Cambridge at the Arm-ECS Research Centre are leading to an environmentally-friendly IoT electronic infrastructure, together with small energy sources critical for many IoT applications.”

He adds, “Designers and users of IoT devices need to be conscious of the cost of energy used to sense, process and communicate data, since not only the size of data matters but also its quality.”

Dr Alexander R. May is a Research Engineer at the IT Innovation Centre, a part of the University of Southampton’s department of Electronics and Computer Science. Prior to joining the IT Innovation Centre he worked immediately post-PhD as a Development Engineer at the venture capital funded start-up company WaveOptics Ltd where he developed computational techniques for the design of diffractive optical elements (DOEs) for the Augmented Reality (AR) market e.g. Google Glasses. He has authored a selection of publications on the topics of optical waveguide and fibre design, as well as teaching methodology in information theory, all with a focus on computational science, which is his passion. Over the years he has also been involved in a broad variety of mechanical and electrical engineering disciplines as well as having had some experience in the merchant navy.  Outside of work he is involved in his local community where he is the Chair of Trustees at his village nursery school.

Research

Research interests

My research interests are all guided by my interest in computational physics and mathematics in simulating and predicting phenomena. At present I am working on computational lingustics and natural language processing (NLP), but I retain an interest in topics ranging from the simulation of guided-wave optical devices to topics in fluid dynamics.
