Anatomy of WiFi Access Traffic of Smartphones and Implications for Energy Saving Techniques
Today's Smartphones are equipped with more features than an average personal computer. They have become the preferred means of communication, and consequently, Smartphone traffic constitutes an increasingly large share of Internet traffic. However, development in battery technology has not kept pace with the developments in other sub-systems of Smartphones, and battery energy puts the ultimate constraint on the availability and performance of Smartphones. For this reason, energy saving techniques for wireless interfaces is more relevant to Smartphones. In this paper, the authors present a detailed analysis of Wi-Fi access traffic of Android based HTC Nexus One, Apple's iPhone 3GS, and BlackBerry 9700 Smartphones for different classes of applications, namely, web browsing, YouTube video playing, and Skype VoIP calling.
