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

Microlocation for Internet-of-Things-Equipped Smart Buildings
TL;DR: It is argued that micro-location-based location aware solutions can play a significant role in facilitating the tenants of an IoT-equipped smart building and will enable the smart building control system through minimal actions performed by the tenants.

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.

A first look at mobile hand-held device traffic
TL;DR: This paper casts a first look on mobile hand-held device usage from a network perspective on anonymized packet level data representing more than 20,000 residential DSL customers, finding that MHD traffic is dominated by multi-media content and downloads of mobile applications.

Over the top video: the gorilla in cellular networks
TL;DR: This first deep dive into cellular video streaming shows that HLS, an adaptive bitrate streaming protocol, accounts for one third of the streaming video traffic and that it is common to see changes in encoding bitrates within a session.

Network-aware forward caching
TL;DR: It is shown in the simulation that a 37% increase to net benefits could be achieved over the standard method of full cache deployment to cache all POPs traffic, and that CDN traffic is much more efficient than P2P content and that there is large skew in the Air Miles between POP in a typical network.

Revisiting Cacheability in Times of User Generated Content
TL;DR: In this article, a large European ISP connecting more than 20,000 residential DSL customers to the Internet, collected in 2009, focused on the most prominent protocols in this environment -HTTP, BitTorrent (BT), eDonkey, and NNTP -and estimate the potential of caching for traffic reduction.
