Abstract:
Advances in wireless communications have increased the popularity of
mobile devices and motivated the development of a large variety of
mobile applications and services. However, reducing the energy
consumption of mobile devices is a major challenge in sustaining the
applications. To address the challenge, we raise the concept of
cloud-based energy-saving services. The services enable the service
provider to help mobile devices save energy when they access Internet
applications. In this talk, I will present the dynamic backlight
scaling service, a prototype service deployed on CHT hicloud to
minimize the energy consumption of the screen backlight when browsing
mobile streaming applications. I will also briefly introduce a number
of on-going research projects for the development of cloud-based
energy saving services and give few demos conducted on HTC Android
smartphones and Apple iPad tablets.
