Define physical context, Computer Engineering

Assignment Help:

Question :

Context aware mobile web applications are the important to achieve ubiquity, device independence and personalization. The context provides detailed information about the environment of a web application and the web application itself. Thereby the context influences not only the requirements as gathered by requirements elicitation but also triggers the actual customisation as soon as the context changes. Context can be divided into a physical and logical context.

a) Define physical context and provide examples of the physical context properties.

b) Using your definition above, and with the help of the Unified Modeling Language (UML), describe how you can design a physical context model for mobile Web applications. You can consider a small well defined set of physical context properties, but as the list is virtually unlimited and certain applications would require specific ones, you have to focus on a model which is extensible.

c) Define logical context and explain why it is a necessary element in context aware mobile Web applications?

d) Explain how the logical context can take the form of profiles.

e) Describe the following profiles
i. Location Profile
ii. Time Profile
iii. User Agent Profile
iv. Network Profile
