  1. Managing location information for billions of gizmos on the move—what's in it for the database folks? Ravi Jain, Christian S. Jensen, Ralf-Hartmut Güting, Andreas Reuter, Evaggelia Pitoura, Ouri Wolfson, George Samaras, Rainer Malaka ICDE Panel, April 5, 2001

  2. Background • In the coming years, wireless computing will find widespread application, and computing will become increasingly pervasive, or ubiquitous. • The wireless revolution promises to have as fundamental an impact on society as the emergence of the commercial Internet. • Industry observes predict that there will be more than a billion wireless ”gizmos” on the Internet within then next few years.  • Gizmos include hand-held devices, e.g, mobile-phone terminals, a diverse range of PDAs, ”wrist watches,” smart clothing, ”cameras,” home appliances, cars, smart dust, etc.  ICDE Panel, April 5, 2001

  3. Background (2) • This proliferation of on-line gizmos is made possible by the continued, ”exponential” advances in electronics. • Technologies such as WAP and Bluetooth, and their successors, will bring about the required connectivity. • Satellite-based positioning systems (e.g., GPS), as well as technologies embedded in the wireless service infrastructures, will enable the positioning of a substantial portion of the gizmos. ICDE Panel, April 5, 2001

  4. Background (3) • In the near future, the Internet will be accessed more frequently from gizmos than from desktop computers. • Some experts pertain that we have yet to come to understand how the above technologies will be used and how they will impact our lives.  • However, near-term applications include • safety and security services • metered services (such as car insurance) • position-enabled tourist services • traffic services and management, • games, etc.  • The gizmos will generate vast quantities of data, either resulting from human interaction, or independently. ICDE Panel, April 5, 2001

  5. Background (4) • The scenario sketched here will see the applications of techniques from a wide range of disciplines in computer science, and it may become a huge area of application for database technology.  • In this scenario, where change is inherently continuous, the capture, modeling, maintenance, and querying of location information may be of critical importance. • The continuous change perhaps raises many research issues. ICDE Panel, April 5, 2001

  6. Panel Question(s) • Is there anything new and challenging in this for the database community? • Where do existing database techniques fall short in meeting the challenges? • What are the new database challenges? ICDE Panel, April 5, 2001
