5. 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.

6. 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.

7. Overview - Volatile system characteristics: - Smart spaces - Device models - Volatile connectivity - Sponatenous interoperation

9. Attributes

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

11. 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.

12. Attributes - 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.

13. Wireless sensor networks

14. Examples of wireless sensor network: Environmental measurement systems Forest fire detection, Greenhouse gas monitoring, Earthquake detection. Related system: GPS - network

18. 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.”
