Speaker: Jean Bolot - Sprint Research Lab

Title: How to own a cellular network in your spare time, and what data
mining has to do with it 


IP and cellular networks used to be isolated from each other. Today,
smart phones with IP addresses routinely access the Internet using
cellular infrastructures. The overlap between the IP and the cellular
worlds raises the question of whether threats or actions from the IP
side could impact the cellular side – in other words, would it be
possible to “own”, or at least to disrupt, a cellular network from a
remote Internet host? I will show how this might be done using paging
overloads, then will derive models of the paging channel to understand
its behavior under load, and finally discuss ways to handle overloads,
intentional or not. One such way relies on mining mobility data and
carefully analyzing the mobility patterns of mobile users nationwide to
derive efficient paging schemes, which in turn increases the robustness
of the network to paging overloads and attacks.

He will conclude the talk with a brief presentation of the research
activities at Sprint in the areas of data mining, security, and wireless


Jean Bolot runs the research lab of Sprint
<http://research.sprintlabs.com/> located in the San Francisco Bay area.
Prior to joining Sprint, he was a founding team member of Ensim, a
Silicon Valley company <http://www.ensim.com/> now with 200 employees in
the area of data center automation. Earlier, he did research at INRIA in
France on Internet measurement and on rate and error control mechanisms
for voice and video and games on the Internet
