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

On the Relation Between Mobile Encounters and Web Traffic Patterns: A Data-driven Study
TL;DR: In this paper, the authors characterize mobility encounters and study the correlation between encounters and web traffic profiles using large-scale datasets (30TB in size) of WiFi and NetFlow traces, for device types grouped into on-the-go Flutes and sit-to-use Cellos.

Fast algorithms for mining association rules
TL;DR: Two new algorithms for solving thii problem that are fundamentally different from the known algorithms are presented and empirical evaluation shows that these algorithms outperform theknown algorithms by factors ranging from three for small problems to more than an order of magnitude for large problems.

Web caching and Zipf-like distributions: evidence and implications
TL;DR: This paper investigates the page request distribution seen by Web proxy caches using traces from a variety of sources and considers a simple model where the Web accesses are independent and the reference probability of the documents follows a Zipf-like distribution, suggesting that the various observed properties of hit-ratios and temporal locality are indeed inherent to Web accesse observed by proxies.

Removal policies in network caches for World-Wide Web documents
TL;DR: Surprisingly, the criteria used by several proxy-server removal policies are among the worst performing criteria in the authors' simulation; instead, replacing documents based on size maximizes hit rate in each of the studied workloads.

TL;DR: This document describes a protocol for transferring unbounded streams of multimedia data that specifies the data format of the files and the actions to be taken by the server (sender) and the clients (receivers) of the streams.
