Bluetooth Connectivity Trace

  • Dataset: UC Davis Haggle - Unitrans Mobility Trace
    Description: This data set includes several traces about the available Bluetooth connectivity during a typical day on the Unitrans bus system at University of California, Davis. The data has been uploaded to the CRAWDAD. The data was collected using Intel iMotes, which contain an ARM core as well as a Bluetooth radio stack. The motes run a simple Bluetooth inquiry program. Periodocally (e.g., every 2 minutes) the device does an inquiry for a duration (e.g., 5 seconds). All devices detected during this inquiry period are noted. These experiments give a list of contacts - with start and end times - that a particular mote has during its lifetime. For each experiment, the polling interval was 2 minutes, and the inquiry duration was 5 seconds.
