  1. Exploiting Infrastructure Resources to support Mobile Computing CS-630 Distributed Mobile Systems Srividya, Ramkishore, Prakash and Kartik

  2. Motivation • Virtual Network Computing • Pebbles • PalmVNC

  3. Objectives • Discover a desktop on a wired LAN • Transport the display of the PDA to desktop • Control the Applications of the PDA

  4. Methodology Phase 1:Simple Advertisement Protocol -Discovery protocol Phase 2:Transport of Display -DDB to DIB format -Encoding algorithm Phase 3- Transport of Control -Trap mouse movement and keyboard events.

  5. Architecture

  6. Virtual Network Computing - only Pixel function used in device driver - compression is application specific - directly deals with frame buffer PDA Display porter - uses pixel and line functions in device drivers. - run-length coding - common APIs Comparison
