New approaches are emerging that will allow wireless systems to safely operate in shared spectrum without interference. A database will be maintained that contains the location and technical characteristics of all devices in the band, and predictive algorithms will determine whether there is risk of harmful interference. Once it exists, an attacker might use this database to obtain sensitive information, perhaps tracking the location of other devices through simple database queries. Is it possible for the database system to make enough information available to support efficient use of shared spectrum without excessive interference, but not enough to compromise location and other sensitive information? In this research, we are developing novel algorithms, developing extensive simulation software to experiment with these algorithms, and evaluating the results. Students should have a programming background, and basic statistics to understand the simulation results.
