There's a 3-day conference called "Future Decoded" running at the Excel centre in London's Docklands, with the Technical Day on 12th Nov having keynote speakers such as Prof Brian Cox, Sir Nigel Shadbolt (founder of the Open Data Institute) and Michael Taylor, the IT Director of Lotus F1.
There's an IoT track in the afternoon which includes sessions from a couple of Microsoft luminaries as well as from Dr Colin Birchenall, the Chief Architect for Future City Glasgow (a £24 million Demonstrator programme funded by Innovate UK) to showcase smart city principles and technologies at scale.
