We report what we believe to be the first measurements of the power consumption of an
802.11 n NIC across a broad set of operating states (channel width, transmit power, rates …

Many applications are enabled by the ability to capture videos on a smartphone and to have
these videos uploaded to an Internet-connected server. This capability requires the transfer …

WiFi networks have enjoyed an unprecedent penetration rate in recent years. However, due
to the limited coverage, existing WiFi infrastructure only provides intermittent connectivity for …

Energy management is a critical issue for mobile devices, with network activity often
consuming a significant portion of the total system energy. In this paper, we propose Catnap …

Desktop computers are an attractive focus for energy savings as they are both a substantial
