Spatio­Temporal Modeling of Traffic Workload in a Campus WLAN

Campus Wireless LANs (WLANs) are complex systems with hundreds of Access Points (APs) and thousands of users. Their performance analysis calls for realistic models of their elements, which can be input to simulation and testbed experiments but also taken into account for theoretical work. However, only few modeling results in this area are derived from real measurement data, and rarely do they provide a complete and consistent view of entire WLANs. In this paper, the authors address this gap relying on extensive traces collected from the large wireless infrastructure of the University of North Carolina.
