  1. 2. Harnessing Latent Mobile Phone Resources For Wireless Telemetry
  2. 3. Mobile Phone Sensor-Net <ul><li>Mobile phones are practically ubiquitous. Everyone carries them and most of them are turned on and connected 24x7. Today's mobile phones, even the least expensive ones, have sensors, spare cycles, and connectivity. These resources can be applied to a wide variety of Social Telemetry Applications , to powerful, and potentially even troubling, effect. We present findings of a real-world deployment of such a system. </li></ul>
  3. 4. Mobile Phone Sensor-Net Analysis P2P Super-Node Basic “edge” (people) Edge-Plus Fixed (anchor) Node <ul><li>Hybrid P2P and client/server </li></ul><ul><li>Autonomous, unattended operation </li></ul>
  4. 5. Mobile Phone Sensor-Net Location Proximity Signaling Basic phone • Bluetooth • SMS
  5. 6. Ambient Awareness Stream <ul><li>Autonomous </li></ul><ul><li>Peer nodes share with each other and upload to cooperating “super-nodes” via Bluetooth </li></ul><ul><li>Edge devices can also act on SMS and other triggers (position reports, geofence, etc.) </li></ul>
  6. 7. Ambient Awareness Stream Location updates time
  7. 8. Ambient Awareness Stream <ul><li>Proximity to other mobiles and fixed (anchor) radios </li></ul><ul><li>Enables “crowd” predictions even if devices are not participating </li></ul>Bluetooth devices coming and going time
  8. 9. Mobile Phone Sensor-Net Theater Mall As a person moves around among other people and things, patterns emerge.
  9. 10. Conclusions <ul><li>Mobile phones can effectively serve as a Sensor-Net , without noticeable impact to normal phone operations, performance, battery life, reliability etc. </li></ul><ul><ul><li>Achieved off-net without carrier participation or cooperation </li></ul></ul><ul><ul><li>Basic phones, “smart” phones, PCs and back-office operating together </li></ul></ul><ul><li>Wi-fi, GPS, and 3G are not required </li></ul><ul><ul><li>Get practical and effective results using low-end phones </li></ul></ul><ul><li>Combining location, time, proximity, and signaling provides significantly richer picture than location alone </li></ul>
