A system for crowdsourcing passive mobile network measurements

In this poster, we build on top of the AntMonitor system and we extend it to add a new module for passive monitoring network performance on mobile devices (w/o middle server). We show that this design is efficient yet powerful, in terms of the performance achieved (compared to alternatives today), realistic measurements (passive monitoring of actual traffic on devices of real end-users), richness of information (fine-grained measurements and rich contextual information available on the devices). We present the system design, a preliminary evaluation, and example applications.
