• Overview

- Mobile Computing Defined by physical movement
of a connected, smart, device.
- Ubiquitous Computing Defined by integration of
computational devices into everyday objects and
environments.

• Overview

- Volatility The nature of distributed
partially mobile systems is changeable and
therefore volatile.
- Issues The constantly changing users and
devices demands a high level of adaptivity and
standardized communication from the network.

• Attributes

- Association Physically driven and location
based. Subject to perpetual change.
- Two main issues Scale and Scope. Handled by
Discovery services

• Attributes

- Interoperation How to best communicate
between distributed devices?
- Data-oriented programming Focused on common
interfaces such as HTTP as opposed to
object-oriented programming.

- Sensing and awareness A wide range of
sensors are interconnected and forward data to
control points.
- Issues Energy conversation vs data
forwarding, quality vs quantity.

From Distributed systems concept and design
...if users carry tags such as RFID tags (for
example, ones embedded in their clothes so that
their smart washing machines can automatically
choose an appropriate washing cycle)...
Similarly, a room could adapt the air
conditioning and lighting settings according to
the recorded preferences of the person within
it.
