  1. Location-based Services& data propagationin ORBIT Henning Schulzrinne Dept. of Computer Science ORBIT NSF site visit - July 14, 2004

  2. Location-based services • Finding services based on location • physical services (stores, restaurants, ATMs, …) • electronic services (media I/O, printer, display, …) • not covered here • Using location to improve (network) services • communication • incoming communications changes based on where I am • configuration • devices in room adapt to their current users • awareness • others are (selectively) made aware of my location • security • proximity grants temporary access • Privacy rules for access to context data ORBIT NSF site visit - July 14, 2004

  3. SUBSCRIBE subscription policy subscriber (watcher) for each watcher event generator policy subscriber filter rate limiter change to previous notification? NOTIFY Location-based services • Based on open and standard protocols • SIP and GEOPRIV for location information • Planning to use outdoor testbed for interpolation-based location determination • Merging information multiple location sensor • indoor & outdoor • mobile & infrastructure • Engaged with privacy policy work in IETF ORBIT NSF site visit - July 14, 2004

  4. Content distribution: network to mobile • Deliver web content to roaming user “weather?” web cache query for all documents multicast 7DS node deliver matching documents ORBIT NSF site visit - July 14, 2004

  5. Mobile to Internet • Email service interface propagate to other pedestrians 7DS MTA encrypt message; encrypt headers with 7DS public key ORBIT NSF site visit - July 14, 2004

  6. ORBIT testbed • On-going work on Linux implementation for n2m and m2n at Columbia • Integration of low-speed (3G/pager) and high-speed networks • Will port to testbed as facilities become available • Planning to use ORBIT PCs at Columbia for testing and local deployment • Later, test in outdoor facility with real data ORBIT NSF site visit - July 14, 2004
