Smartphone Background Activities in the Wild: Origin, Energy Drain, and Optimization
TL;DR: A large-scale measurement study that performs an in-depth analysis of the activities of various apps running in background on thousands of phones in the wild, and a metric to measure the usefulness of background activities that is personalized to each user is developed.
Patent
System and method for energy usage accounting in software applications
Yu Charlie Hu,Abhinav Pathak +1 more
TL;DR: In this paper, a method for generating an energy usage profile for a software program executed in a computing device includes generating a call trace of an executed system call, identifying the first power consumption and duration of a first power state due to the first system call using a model, and generating an EE profile for the software program.
Proceedings ArticleDOI
A case for unsupervised-learning-based spam filtering
TL;DR: To the knowledge, SCA is the first unsupervised spam filtering scheme that achieves accuracy comparable to the de-facto supervised spam filters by explicitly exploiting online campaign identification.
Patent
Systems and methods of detecting power bugs
TL;DR: In this article, a computer-implemented method for analyzing a computer code includes generating a control flow graph for at least a portion of the computer code at a processor, which is used to identify power bugs.
Patent
System and methods for power and energy modeling in computing devices using system call tracing
Yu Charlie Hu,Abhinav Pathak +1 more
TL;DR: In this paper, the authors present a power consumption and energy usage model for a computing device that includes monitoring of the power consumption of the computing device with an external power monitor when the device is in a base power state.
