  1. Data Management in Mobile and Wireless Environments George Samaras University of Cyprus 23-10-2006 Dagstuhl Oct. 2006

  2. The DBMS Group & Collaborators • Panagiotou Christoforos • Dimos Georgiadis • Papastavrou Stavros • Polyviou Stavros • Panyiotou Andreas • Xariklia Skoutelli • Maria Andreou • Odysseas Papapetrou • Karenos Kyriakos • Panayiotis Germanakos • Evaggelia Pitoura • Panos Chrysanthis • Skevos Evripidou • Andreas Pitsillides • Andreas Andreou Dagstuhl 2006

  3. Palm WinCE Tablet Smartphone Mobile Fixed Network Laptop PDA Mobile The Mobile Environment • Mobility • Mobile Devices, • Wireless Links weak connectivity Disconnection Repeat Dagstuhl 2006

  4. Motivation the characteristics and limitations of this environment affect a number of aspects of distributed computing and give birth to a number of interesting research challenges Wireless mobile computing breaks the stationary barrier and allows users to compute and access information anywhere, anytime and from any device However Dagstuhl 2006

  5. The characteristics-limitations(and opportunities) • Wireless link • limited bandwidth • Asymmetry • High bandwidth variability • high latency • high cost • poor reliability • Frequent disconnections • Predictable disconnections • Mobility • System configuration not static • Heterogeneity • Hand-off • Location management • Mobile elements • resource-poor: • Limited memory • Limited computational power • Small screen • Limited battery life • unreliable • portability problems Dagstuhl 2006

  6. Totally related to create a new distributed paradigm Dagstuhl 2006

  7. The Research Flow: system’s area itinerary Dagstuhl 2006

  8. The Research Flow: user’s aspect area itinerary Dagstuhl 2006

  9. What are we working on?? • Personalizing the wireless user • Pervasive visual query language • QBB and Active Folders • Directory services for mobile services • Extend our work on Mobile views • Mobile agent-based pervasive middleware • Location-based Web crawling • eHealth • Sensors and query processing (Views) • Web Dynamic Content • Mobile and Internet commit processing Dagstuhl 2006

  10. Final word “The problem in times of turbulence is not the turbulence; it is acting with yesterday’s logic.” Peter Drucker If you’re trying to look far ahead, and what you see seems like science fiction, it might be wrong. But if it doesn’t seem like science fiction, it’s definitely wrong. Christine Peterson, Foresight Institute Dagstuhl 2006

  11. In the meantime... • Rersearchers and Professor are working hard to develop newer and better things for you... Dagstuhl 2006
