Some scenarios and Implications (1/2)

• 1. Locate/track somebody
• Where did I leave my laptop?
• Where is Pluto running around? (IP-device in dog
  collar)
• Implications
• IP-device able to retrieve/receive (periodically)
  location information of another IP-device
• 2. Broadcast information to devices in a certain
  region
• Emergency warning of snowstorm
• Local site shutdown warning
• Implications
• IP-device can determine which IP-devices are in a
  certain region
• (Client IP-device can decide whether to publish
  its existence in a certain region)

3
Some scenarios and Implications (2/2)

• 3. Retrieval of location based information and
  service
• Mobile user wants to order local taxi, find
  closest pizzeria
• User wants to obtain regional (web) information
  about Helsinki
• Implications
• Service must be able to obtain client location
• Find server providing service for the specific
  region/location
• 4. User subscribed location based services
• IETF-participator wants to be notified about
  sights in Adelaide when walking past them
• Implications
• Service must obtain client location periodically
  and/ordetermine if it is still within the region
  for the service
• Find server providing service for the specific
  region

What is needed?

• Communicating location of an IP-device to another
  IP-device
• IP-device can provide it or announce from where
  to get it
• The other IP-device can request or look it up
• Finding IP-devices located in a certain region
• Important ...
• Finding services available for a certain
  location/region
• virtually they can reside where ever in network
• Other issues
• location data formatsgranularity challenging -
  conversion services can help
• user should be in control - to whom, what
  accuracy, for what use
