  1. Context Architectures Using Web Services Candidate: Alvaro E. Escobar Advisors: Dr. Maria Petrie Dr. Eduardo Fernandez Department of Computer Science and Engineering Florida Atlantic University, Boca Raton FL. 01/26/2006

  2. Agenda • Review the following papers: • [Cha04] T. Chaari, F.Laforest, A. Celentano. “Design of Context-Aware Applications Based on Web Services”. LIRIS. Dipartimento di Informatica. INSA Lyon, France • [Soa02] S. Soares, P. Borba. “PaDA: A Pattern for Distribution Aspects” Proceedings of: Second Latin American Conference on Pattern, 2002 • [Rae05] M. Raento, A. Oulasvirta, R. Petit, H. Toivonen. “ContextPhone: A Prototyping Platform for Context-Aware Mobile Applications”. IEEE Pervasive Computing, 2005 • [Str05] M. Strimpakou, I. Roussaki, C. Pils, M. Angermann, P. Robertson. “Context Modelling and Management in Ambient-Aware Pervasive Environments ”, Location- and Context-Awareness Proceedings : First International Workshop, LoCA 2005, May 12-13, 2005.

  3. Design of Context-Aware Applications Based on Web Services [Cha04] • Development of context-aware apps. • Architecture supporting context-awareness at run-time. • design the application to be context-aware. • Web services is widespread and “loosely coupling” approach to integration of application

  4. Design of Context-Aware Applications Based on Web Services • Service Oriented Architecture (SOA) [Cha04] • Context Capturing • Context Interpreting • Context Modeling • Context Dissemination • Context Adaptation • Data flow (content) • Visualization (UI) • Application behavior (service)

  5. Agenda • Review the following papers: • [Cha04] T. Chaari, F.Laforest, A. Celentano. “Design of Context-Aware Applications Based on Web Services”. LIRIS. Dipartimento di Informatica. INSA Lyon, France • [Soa02] S. Soares, P. Borba. “PaDA: A Pattern for Distribution Aspects” Proceedings of: Second Latin American Conference on Pattern, 2002 • [Rae05] M. Raento, A. Oulasvirta, R.

  6. ContextPhone: A Prototyping Platform for Context-Aware Mobile Applications [Rae05] • Software platform running on Symbian OS (Nokia Series 60 Smartphone). • Design goals: • visualizes Context as a resource. • incorporate existing applications. • fast interaction and unobtrusiveness. • ensure robustness. • enable rapid development

  7. ContextPhone: A Prototyping Platform for Context-Aware Mobile Applications[Rae05] • Modules [Rae05] • Sensors • Communications • Customizable applications • System services

  8. Agenda • Review the following papers: • [Cha04] T. Chaari, F.Laforest, A. Celentano. “Design of Context-Aware Applications Based on Web Services”. LIRIS. Dipartimento di Informatica. INSA Lyon, France • [Soa02] S. Soares, P. Borba. “PaDA: A Pattern for Distribution Aspects” Proceedings of: Second Latin American Conference on Pattern, 2002 • [Rae05] M. Raento, A. Oulasvirta, R.

  9. Context Modelling and Management in Ambient-Aware Pervasive Environments[Str05] • Presents a Context Model integrated into a pervasive service platform(DAIDALOS–European IST project) • DAIDALOS (www.ist-daidalos.org): • Designing • Advanced network • Interfaces for the • Delivery and • Administration of • Location independent • Optimized personal • Services

  10. Context Modelling and Management in Ambient-Aware Pervasive Environments[Str05] • DAIDALOS University Scenario: • Organization of daily life at university (friends, appointments and reservations, classes, projects, exams, entertainment) • Locating people and devices on campus, checking availability, discovering local services. • Personal broadcasting (of classes and speeches)

  12. Context Modelling and Management in Ambient-Aware Pervasive Environments[Str05] • Context Management Subsystem Architecture [Str05]

  13. Conclusions • Context is a fundamental concept in mobile systems. • Different researchers use different variations of context. • Web services is the widespread approach to application integration. • Integrate Web Services into our Context Model for easier application integration. • Create a Context Architecture incorporating WS.

  14. Future Work • Context-Aware Web Services Distributed and Parallel Databases Journal - Submission deadline: March 15, 2006. • AMCIS Minitrack on Mobile Services - Submission deadline: March 1, 2006. • Dissertation document completed by end of Summer ’06.
