Abstract
Portable audience measurement architectures and methods for portable audience measurement are disclosed. A disclosed system contains a plurality of portable measurement devices configured to collect audience measurement data from media devices, a plurality of data collection servers configured to collect audience measurement data from the plurality of portable measurement devices, and a central data processing server. A portable measurement device establishes a communication link with a data collection server in a peer-to-peer manner and transfers the collected audience measurement data to the data collection server. Because the portable measurement device is not dedicated to a particular local data collection server, the portable measurement device periodically or a periodically broadcasts a message attempting to find a data collection server with which to establish a communication link.
