A network-assisted system for energy efficiency in mobile devices

摘要: We present the design and implementation of Scepter, a system with explicit infrastructure support to reduce energy consumption improve battery life mobile devices. Scepter focuses on effective techniques that can total number bits transmitted communicate same information from device base station. combines multiple into single unified architecture by utilizing stateful proxy located within close wireless intentionally introduces asymmetries in communication tasks between provide greater advantages device. In this work, we have implemented all capabilities as various kernel- user-level enhancements. Our detailed evaluation demonstrates performance Scepter. experiments different conditions traffic patterns, improves these devices 15% 54%.
