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



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)

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


ContextPhone: A Prototyping Platform for Context-Aware Mobile Applications [Rae05]

  • Modules [Rae05]

    • Sensors
    • Communications
    • Customizable applications
    • System services

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


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)
