Network Support for Mobile Devices and Applications: Infrastructural Limitations

Speaker: Chunyi Peng UCLA
Time: 2013-04-15 10:00-2013-04-15 11:00
Venue: FIT 1-222


 We are experiencing the explosive growth of mobile devices and mobile apps. Recent market statistics show that, 770M smartphones and 191M tablets have been shipped in 2012, and both Apple Store and Google Play have exceeded 40B/25B downloads of mobile apps. However, our study shows that, the current network and systems architecture are not adequate to bring such devices and mobile apps to prime stage. In this talk, I will describe my recent work on network support for mobile devices and mobile apps. Using measurements on operational networks, I will reveal the infrastructural limitations of current 3G/4G cellular infrastructure, as well as WiFi networks, when supporting mobile devices and apps. The issues range from accounting errors, interplay of voice and data, to energy efficiency and latency requirement. For each identified issue, I further describe its root cause and my remedy proposal. Finally, I will describe our ongoing effort to build the mobile cloud platform, which seeks to offer “anytime, anywhere, any device” online data services to mobile devices and apps.
