Challenges

  • reliability
  • privacy and security
  • power management - not all devices are battery powered
  • diversity - both a challenge and an opportunity
  • fast deployment - disaster recovery scenarios

Medical devices

  • ECG
  • SpO2
  • Blood pressure (CardGuard)
  • Motion analysis board
    • for Parkinson's, to identify uncontrolled shaking and fine-tune dosage -- Code blue
    • for detecting falls -- UVA

Groups

  • University of Virginia: Alarm-NET
  • Intel Research Seattle
  • University of Washington
  • University of Rochester
  • Harvard University
  • John Hopkins: AID-N

CodeBlue

SMART (Scalable Medeical Alert Response Technology)

  • Domain: disaster recovery, triage
  • Network architecture: 802.11b
    • Two types of devices: patient monitoring and caregiver
  • Devices: PDAs
  • Sensors:
    • medical: SpO2, ECG from MIT
  • Functions:
    • vital sign monitoring
    • vital sign analysis & alarms
    • localization

Notes:

Good background section.

Alarm-NET

  • Domain: assisted living, circadian activity rhythms (CAR)
  • Network architecture:
    • Spans body networks, sensor networks and IP networks
    • Query service to collect data
    • Emphasis on dynamic security
    • Use CAR information for security and power management
  • Devices: heterogeneous - motes, PDAs and PCs
  • Sensors:
    • medical: pulse, blood oxygenaton
    • non-medical: temperature, light, infrared motion
