AntMonitor is a system for passive monitoring, collection, and analysis of fine-grained, large-
scale packet measure ments from mobile devices. The system may be imple mented on top
of a VPN-based service and using two possible architectures: Client-Server or Mobile-Only.
A cur rent implementation of the Mobile-Only design may out perform other mobile-only
approaches: it may achieve, for example, 2x and 8x faster (down and uplink) speeds, and
close to the raw no-VPN throughput, while using 2-12x less energy. Ant Monitor can scale to …

In this thesis, we propose AntMonitor–a complete system for passive monitoring, collection,
and analysis of fine-grained, large-scale packet measurements from mobile devices. We
design AntMonitor as a VPN-based service, and we develop and compare two versions of
the architecture, Client-Server and Mobile-Only. We show that the AntMonitor Mobile-Only
prototype significantly outperforms the Client-Server one, as well as all comparable state-of-
the-art approaches wrt throughput and energy. It achieves speeds of over 90 Mbps …
