outline
Outline
  • Goals
  • Mobile internet & wireless technologies
  • Portable devices and their hierarchy
  • Web system architecture
  • WAP system architecture
  • Examples
  • Conclusions & future work
goals
Goals
  • Integrate Condor in the mobile internet world.
  • Allow different levels of user accessibility.

Or: ¿what is missing in Condor to face the mobile Internet?

mobile internet
Mobile Internet
  • Internet technologies and services for mobile devices.
  • Mobile-Internet is driven by the convergence of:
    • Wireless technologies
    • Portable devices
wireless technologies
Wireless technologies
  • They will enable easy interconnection of a wide range of portable computing devices.
  • Present: 2G systems (GSM, IS-95).
  • Incoming: Wireless LAN (IEEE 802.11), Bluetooth, HomeRF, LMDS, 3G systems (UMTS).
mobile devices
Mobile devices
  • (Wireless) laptops (first mobile solution)
  • PDAs (Palm pilot, pocketPC,...): user interface with limited capabilities. Handwriting recognition.
  • WAP-enabled mobile phones: user interface even more limited.
  • Next: Wearable computers (less comfortable, need goggles). Speech recognition.

Condor

Condor

  • Program tuning:
  • Final-stage programming utility
  • Small modifications in source code
  • Program generation
  • Check queue status
  • Remove, hold & release jobs
  • Submit new jobs
  • Alarm on job finish

Usability

  • Check queue status
  • Remove, hold & release jobs
  • Submit new jobs
  • Program tuning

layer implementation
Layer implementation
  • PDA layer is implemented as a web service. This has many advantages:
    • Familiar interface.
    • WAP system implementation is a subset of PDA system implementation (compatibility & reutilization)
    • Almost all PDAs have web browsers (platform independence)
  • WAP layer uses WML browsers.

conclusions future work
Conclusions & future work
  • Definition of usability-hierarchy for mobile internet devices
  • Assumption: Cell phone/PDA units everywhere
  • Remote execution of most functions
  • Other paradigms: Interface servers (X-Windows, Citrix)?
