1. 788.11J Presentation CodeBlue: A sensor network for medical Care Ren-Shiou Liu

2. The Main Idea A reliable and scalable hardware and software platform for medical sensor networks

3. The Challenges Wearable sensor platforms Support multicast routing topologies Device mobility A wide range of data rates Security

4. Medical sensors Wireless EKG Wireless Pulse Oximeter Pluto mote

5. TinyADMR SensorsReceivers Broadcast channel Query Patient status

6. The MoteTrack location system B1, B2 and B3 are beacons nodes which broadcast beacon messages Mobile node M aggregates beacon messages into a signature. Comparing the signature and reference signatures stored in beacons nodes, the location of mobile nodes can be determined

7. Innovation Wearable wireless sensors Ad-Hoc multicast routing on resource-limited sensor nodes MoteTrack: A robust, decentralized approach to RF-based location tracking Integration with iRevive, PDA-based patient care record system
