Abstract

In addition to continuously receiving streaming data, a mobile device
in popular Internet P2P streaming applications also needs to upload to
other peers and exchange control information (e.g., buffermaps and
file chunk requests) with neighbors for such download and upload. This
leads to excessive battery power consumption on the mobile device.

In this study, we first conduct Internet experiments to study in-depth
the impact of control traffic and uploading traffic on battery power
consumption with several popular Internet P2P streaming applications.
Motivated by measurement results, we design and implement a system
called BlueStreaming that effectively utilizes the commonly existing
Bluetooth interface on mobile devices.  Instead of activating WiFi and
Bluetooth interfaces alternatively, BlueStreaming keeps Bluetooth
active all the time to transmit delay-sensitive control traffic while
using WiFi for streaming data traffic.  BlueStreaming trades
Bluetooth's power consumption for much more significant energy saving
from shaped WiFi traffic. To evaluate the performance of
BlueStreaming, we have implemented prototypes on both Windows and Mac
to access existing popular Internet P2P streaming services.  The
experimental results show that BlueStreaming can save up to 46%
battery power compared to the commodity PSM scheme.
