  1. Context-aware Instant Messenger for Mobile Users CS Final Year Project (Year 2006-2007) Supervisor: Dr.Cho-Li Wang

  2. The Future Landscape –Pervasive Computing Environment • Everything becomes smart and connected • The pen, the toy, the wall, the living room and “you” • They “talk” and cooperate to make your life better

  3. The Project Goal P – Person D – Device S – Software O – Other entities • Pervasive Communication • Anytime, anywhere • “Anything” • In a buddy-like way • Appropriate • Knowing when, where, how • Familiar • “gd nite & cu tmr” • Use your own dialect • This project looks at the potential usage of IM on mobile devices in future pervasive environments.                

  4. Pushing IM into PCE • Everything as your buddy and can be communicated using real-time message exchange • Three main features • Context-aware presence management • Context as presence • Different buddies see different status • Resource buddy services • extend the concept of “buddies” to all software and hardware components in your working space • IM as the unified communication interface • Buddy understands your dialect • Dynamic grouping • Location-based Grouping (“buddy discovery”) • Activity-based Grouping (“task centric”)

  5. Extended IM Framework (Interaction between IM server and client) SIM Client SIM Server Context-aware Supporting Middleware (Context modeling, reasoning, event monitoring…) Context Providers (Gather context data from various sources and provide them in various formats…) Sensor Sensor Sensor Overview of the architecture • Extend the IM framework and implant context-aware behaviors • Separate context provision from context consumption • Everything’s behind an SIM client • Distributed Servers Architecture

  6. Software and Hardware Needed • Hardware : • iPAQ PDA • Network: WLAN (802.11) + BlueTooth • Sensor : RFID • Software • Rule-based reasoning engine • Tools: Jena, Protégé • Language: Java, OWL (for building context model) • IM • Jabber Instant Messaging system, http://www.jabber.org/ • XML-formatted message exchange
