1. Agenda Why context-aware apps and Web Services?
Review context model with functions added.
Devise the Web Services and architecture.

2. Context Architectures Using Web Services
9/15/2005
Development of context-aware apps.
Architecture supporting context-awareness at run-time using web services.
design the application to be context-aware.
Web services is widespread and “loosely coupled” approach to integration of applications.
Identify patterns to support context using web services.
The development of context-aware applications requires two goals to be assessed: (1) how to design an architecture supporting context-awareness at run-time, and (2) how to design the application itself in order to be context-aware. Web services is widespread and is considered today a viable architecture for evolving applications, mainly due to its “loosely coupling” approach to integration of application functions.

3. Context Architectures Using Web Services
Context is a fundamental concept in mobile systems.
Different researchers use different variations in models and concepts of context.
Web services is the widespread approach to application integration.
Desired to integrate Web Services into our Context Model for easier application integration.
Create a Context Architecture incorporating Web Services.
Simulation to validate the model in its functional parts.
