  3. Concept • Give consumers access to their personal physiological data. • Wireless network of sensors on the body to process and record EKG, pulse oximetry, and location data. • More flexible than competing products, with an easier-to-use User Interface.

  4. Goals • Provide accurate data to the user • Reliable data transfer from the device to the computer • User friendly User Interface • Accurate data analysis using graphs

  5. Architecture

  6. Components

  7. Experimental Campaign • Sensor Nodes • Data Transmission (Reliability)–Test for dropped packets and re-transmits. • Sensor Server • Startup (Reliability)–Devices activate in a coordinated fashion. Data log system starts cleanly. Test repeated startup/shutdown sequence. • Pairing with computer/Data upload (functionality)–Test connection between computer and Sensor server; Specifically, try the cases of sensor server power failure, computer power failure, Bluetooth interference. • Test aggregating data (Functionality)-we want all data to be transmitted well -collect two or more types of data and upload all of them fault-free. • Shutdown (Reliability)–Test clean shutdown case (Sensor server issues shutdown commands to motes), power failure recovery (of motes), and salvage of partial data in gumstixpower failure. • Computer • Error catching (Reliability) –Test computer side code for correct response to corrupted or illegal data.
