Carlos Manuel Rodrigues Machado Autonomic Ubiquitous Computing

The concept of device information broadcast, to the communication medium, as events was
used as an approach to: inter-connect future systems, monitor correct operation of the system
devices, capture raw data for estimation of context; allow the visualization of system feedback in
user interface devices.
Finally, an algorithm using artificial neural networks in combination with simple statistics was
developed which allowed the house to learn the routines of its inhabitants, making it truly intelligent
by embedding the knowledge about patterns of activities of the users in the devices scattered in the
environment, increasing their comfort and, at same time, leading to more energy efficiency. The
analysis of the data captured, during two complete years, shows that the reduction of power
consumption could be as high as 50%, depending on the profile of the usage of the light.
