Technology Applications

• Group 1

2
Needs

• Voice
• Text
• Location based info
• Remote automation (lights, etc.)
• Support for muitiple/different users/access
  models in a ubiquitous network
• Device ergonomics / convenience / visual appeal

3
Applications

• Ubiquitous information (retreival/status)
• Location based devices
• Bus schedules at bus stations
• Locality-based information
• How do you do status
• Authentication (ski passes, etc)
• Safety / monitoring / tracking
• Privacy

4
Applications (cont.)

• Virtual graffiti
• Wireless power

6
Challenges

• Scalability problem
• How can we do these things without 1000s of
  nodes?
• High production for PN3 is important
• Power issue becomes critical
• Reprogrammability
• Fault tolerant, robust networking

7
Challenges (cont.)

• Mesh power-forwarding?
• Asynchronous nodes only power up when theyve
  scavenged enough
• Powerpoint-to-chip
