摘要

本文研究了编解码器对VoIP应用能耗的影响。这些应用程序越来越多地在笔记本电脑、智能手机和平板电脑等依赖电池的设备用户中扩展。我们提供了一种方法来比较给定设备的不同VoIP编解码器的能源效率。这允许用户和开发人员通过编解码器选择最小化能耗，并在qos带宽平衡中引入一个新的变量，该变量传统上导致VoIP应用中的编解码器选择。我们的研究结果表明，编解码器对便携式设备的VoIP软件的能耗有显著影响。

Impact of VoIP codecs on the energy consumption of portable devices

In this paper we investigate the influence of the codecs into the energy consumption of VoIP applications. These applications are increasingly extended among users of battery- dependent devices such as laptops, smartphones and tablets. We provide a methodology to compare the energy efficiency of different VoIP codecs for a given device. This allows users and developers to minimize the energy consumption by codec selection, and introduces a new variable into the QoS-bandwidth balance that has traditionally lead the codec selection in VoIP applications. Our results show that the codec can have a significant impact on the energy consumption attributable to the VoIP software of the portable device.
