首发时间:2014-12-01
摘要:如今云服务随着他的方便性和安全性的提高,已被大部分人所接受,并且逐渐融入到人们的日常生活中。与云端进行交互的过程主要包括两部分:数据压缩和数据传输。前者主要是压缩需要传输的数据,以便于节约传输时间;后者则是将压缩完的数据传输到后台服务器进行下一步处理。这两个子过程都是相当耗电的过程,对于智能手机这种电量有限的智能设备,这极大的降低了智能手机的用户体验。本文提出了一种用于智能手机上的测量智能手机耗电量的测试方法,并且为这两个交互的子过程分别创建了耗电模型。为了清晰的分析整个过程的耗电量,首先拆分出两个子过程,然后分别对其进行分析。然后根据提出的测试方法分别对两个子过程进行电量测量。根据所测得的数据,为整个交互过程创建了一个耗电模型。最后,将耗电模型应用到不同的压缩工具和传输速率上,然后挑选出最节能的压缩工具和传输方式。最终的数据显示,当传输速率达到800KB/s时,zip的耗电量是最低,并且仅为第二名的52.4%。

Power Consumption of Compression Tools Based on Smartphones
Abstract:Cloud service has widely been widely used in people's daily life for its convenience and security. In general, there are two sub processes in the course of the interaction mobile devices and cloud servers: data compression and transmission. The former compresses data to save transmission time and data traffic. The latter push data to cloud servers for further processing from the mobile devices. However, both processes operate at a high energy consumption, which introduce extra energy cost to the energy-hungry mobile device and reduce the degree of user experience. In this paper, we present a test methodology for evaluating energy cost on mobile devices, and propose a power module for analyzing the energy consumption during data compression and transmission. In order to analyze the power consumption, we first investigate these two sub processes-data compression and data transmission in detail. Then we present an energy measurement methodology to perform energy detection for components on smartphones. Then we propose an energy cost model for data compression and transmission to describe the energy consumption during the interaction process. Finally we apply the energy measurement methodology to the experiment for different data compression and data transmission methods, and find an energy efficient data compression method for these two sub processes. The result shows when the transmission rate reaches 800KB/s, the zip method only costs 52.4% energy of the second energy-efficient method.
