Mobile network traffic is continuously growing and evolving, pushed by new usages (e.g. augmented reality) and new users (e.g. machine-type communications). Understanding how the user demand varies in space and time is the first step in the design of a flexible and reconfigurable mobile network, supporting a dynamic management of network resources that adapts to the spatio-temporal fluctuations of the mobile demand. In this talk, I will address the problems of classification and anonaly detection in mobile traffic data, by discussing how we can build typical demand profiles, in space and time. I will present two approaches, one based on hierarchical clustering and the other on spectral decomposition, evaluated using extensive real-world data. These approaches bring out a limited number of time periods that show a similar stable spatial distribution of the mobile demand, and highlight categories of urban areas characterized by analogous demand evolution over time. These results have applications beyond the networking field, e.g. in transportation, sociology or urban planning.

Speaker: Razvan Stanica is an associate professor with the Telecommunications department at INSA Lyon and a researcher in the Inria Agora team. He received MSc degrees from Polytechnic University of Bucharest, Romania, and from the National Polytechnic Institute of Toulouse, France, where he also obtained his PhD in 2011. His research interests cover algorithmic and architectural aspects of wireless networks in dynamic environments.
