Sammanfattning

Web technology underpins many interactive mobile applications. However,
energy-efficient mobile web interactions is an outstanding challenge. Given
the increasing diversity and complexity of mobile hardware, any practical
optimization scheme must work for a wide range of users, mobile platforms
and web workloads. This paper presents CAMEL, a novel energy optimization
system for mobile web interactions. CAMEL leverages machine learning
techniques to develop a smart, adaptive scheme to judiciously trade
performance for reduced power consumption. Unlike prior work, CAMEL
directly models how a given web content affects the user expectation and uses this to guide energy optimization. It goes further by employing transfer learning and conformal predictions to tune a previously learned model in the end-user environment and improve it over time. We apply CAMEL to Chromium and evaluate it on four distinct mobile systems involving 1,000 testing webpages and 30 users. Compared to four state-of-the-art web-event optimizers, CAMEL delivers 22% more energy savings, but with 49% fewer violations on the quality of user experience, and exhibits orders of magnitudes less overhead when targeting a new computing environment.
