Mobility in a large-scale WiFi network: from syslog events to mobile user sessions.

Network management logs from a campus 802.11 network of nearly 4,500 ARUBA access points at the University of Massachusetts Amherst are presented. The processing steps to transform the logs from a series of individual network events, into user session trajectories are described and preliminary results are shown based on the user mobility characteristics. We plan to release a differentially private set of user trajectories for use by the research community which we hope can provide valuable insights into user mobility characterization.
