Abstract

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

一种用于移动设备中能源效率的网络辅助系统

我们介绍了Scepter的设计和实现，这是一个具有明确基础设施支持的系统，可以降低能源消耗并提高移动设备的电池寿命。Scepter专注于有效的技术，这些技术可以减少从移动设备到基站传输相同信息所传输的比特总数。Scepter通过利用靠近无线基站的基础设施中的有状态代理，将多种技术结合到一个统一的体系结构中。Scepter有意在移动设备和有状态代理之间的无线通信任务中引入不对称，为移动设备提供更大的能量优势。在这项工作中，我们将Scepter的所有功能实现为各种内核级和用户级增强。我们的详细评估证明了Scepter的性能优势。在不同无线条件和流量模式的各种实验中，Scepter将这些设备的能耗提高了15%到54%。
