The
proxy always selected the estimated optimal burst interval
for each test case. We measured the current draw of the
smartphone and collected traffic traces and signaling logs
during each streaming session. Current was measured using
external meters connected to the smartphone’s power input.
We used in total four different smartphones in the measurements:
Nokia N900 (Maemo), Nexus One (Android 2.3.6),
Lumia 800 (WP 7.5), and HTC Velocity (Android 2.3.7) as
the only LTE capable phone.
