Context Computing Based on Wireless Features
This event took place on Wednesday 04 July 2012 at 11:30

We are surrounded by sensing and actuating wireless devices. This environment is characterised by a high number of devices which can be reportedly explored as atypical ubiquitous sensing devices such as the power supply system, light bulbs or electromagnetic noise. A further ubiquitous sensing source,   incorporated by nearly all electronic devices, and presumably present in all devices that will constitute the Internet of Things, is the RF-interface. The RF-interface is a rich communication medium but also a rich sensing device. Its physical layer capabilities for the description of information and as a fingerprint of environmental situation are only partially explored currently. Environmental changes and situations alter the propagation path of electromagnetic waves and therefore channel characteristics at an RF-receiver, which can, in turn, be utilised for ubiquitous applications. Although this rich context source can support applications in a multitude of ways, its potential is seldom fully exploited. We explore the RF-channel for 1/ the detection of actions and environmental situations from RF features 2/ the reduction of computational load in a distributed context computation 3/ spontaneous, unattended secure device interaction.

Maven of the Month

We are also inviting top experts in AI and Knowledge Technologies to discuss major socio-technological topics with an audience that comprises both members of the Knowledge Media Institute, as well as the wider staff at The Open University. Differently from our seminar series, these events follow a Q&A format.
