Outline

• Goals
• Mobile internet wireless technologies
• Portable devices and their hierarchy
• Web system architecture
• WAP system architecture
• Examples
• Conclusions future work

3
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?

4
Mobile Internet

• Internet technologies and services for mobile
  devices.
• Mobile-Internet is driven by the convergence of
• Wireless technologies
• Portable devices

5
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).

6
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.

7

• 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

8
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

• 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)?
