CodeBlue

  • AMDR Routing:
    • support for pub/sub
    • routing state proportional to the # of publishers (an entry in the table for each publisher)
    • route discovery initiated when a device requests to publish data, requires flooding
    • a subscriber that wants to receive data from a channel sends a route reply on the reverse path (handles asymmetric links)
    • routes are updated through periodic floods (every 15s)
    • negative results on mobility
    • path metric (PDR)
      • for each link, estimate LDR by mapping the measured LQI to a link delivery estimator. This model is determined empirically.
      • PDR is the product of all LDRs of the links along the path
    • see CodeBlue Technical Report

SMART

Scalable Medical Alert Response Technology (SMART)

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
