TLDR
A novel Operating System (OS) fingerprinting methodology to distinguish different types of wireless devices (smartphone vs laptops) as well as operating system instances (iOS, Android, BlackBerry etc.).Abstract:
In this work we present the differences and similarities of the web browsing behavior in most common mobile platforms. We devise a novel Operating System (OS) fingerprinting methodology to distinguish different types of wireless devices (smartphone vs laptops) as well as operating system instances (iOS, Android, BlackBerry etc.). We showcase that most of the multimedia content in smartphone devices is delivered via Range-Requests, and a large portion of the video transfers are aborted. We also show that laptop devices have more intelligent browser caching capabilities. We investigate the impact of an additional browser cache, and demonstrate that a 10MB browser cache that is able to handle partial downloads in smartphones would be enough to handle the majority of the savings. Finally, we showcase that caching policies need to be amended to attain the maximum possible savings in proxy caches. Based on those optimizations the emulated proxy cache provides 10%-20% in bandwidth savings.read more

Measurement and Analysis of Mobile Web Cache Performance
TL;DR: This paper builds a new cache analysis model and study the upper bound of how high percentage of resources could potentially be cached and how effective the caching works in practice, and identifies two major problems -- Redundant Transfer and Miscached Resource, which lead to unsatisfactory cache performance.

CacheKeeper: a system-wide web caching service for smartphones
Yifan Zhang,Chiu Tan,Li Qun +2 more
TL;DR: Evaluation on 10 top ranked Android apps shows that the CacheKeeper prototype can save 42% networks traffic with real user browsing behaviors and increase web accessing speed by 2x under real 3G settings, and experiments show that the prototype incurs negligible overhead on cache misses.

Network-aware partial caching for Internet streaming media
TL;DR: A novel cache architecture and associated cache management algorithms that turn edge caches into accelerators of streaming media delivery are presented, which allows partial caching of media objects and joint delivery from caches and origin servers.
