Welcome to CRAWDAD

CRAWDAD is the Community Resource for Archiving Wireless Data At Dartmouth, a wireless network data resource for the research community. This archive has the capacity to store wireless trace data from many contributing locations, and staff to develop better tools for collecting, anonymizing, and analyzing the data. We work with community leaders to ensure that the archive meets the needs of the research community.

CRAWDAD is grateful to its current and past sponsors.

new CRAWDAD dataset - Netalyzr Android data - March 31, 2015

A new dataset has been added to CRAWDAD.

Mobile data collected using the Netalyzr for Android App.

Contributed by Narseo Vallina-Rodriguez, Srikanth Sundaresan,
Christian Kreibich, Nicholas Weaver, Vern Paxson.

This dataset was collected by the ICSI Netalyzr app for Android to
develop a characterization of how operational decisions, such as
network configurations, business models, and relationships between
operators introduce diversity in service quality and affect user
security and privacy. We delve in detail beyond the radio link and
into network configuration and business relationships in six
countries. We identify the widespread use of transparent middleboxes
such as HTTP and DNS proxies, analyzing how they actively modify user
traffic, compromise user privacy, and potentially undermine user
security. In addition, we identify network sharing agreements between
operators, highlighting the implications of roaming and characterizing
the properties of MVNOs, including that a majority are simply
rebranded versions of major operators. More broadly, our findings
using this data highlight the importance of considering higher-layer
relationships when seeking to analyze mobile traffic in a sound

The dataset is used for a forthcoming MobiSys paper entitled "Beyond
the Radio: Illuminating the Higher Layers of Mobile Networks".

new CRAWDAD dataset - Facebook and Bluetooth encounters - February 10, 2015

A new dataset has been added to CRAWDAD.

Traces of Bluetooth encounters, Facebook friendships and interests of
a set of users collected through SocialBlueConn application at
University of Calabria

Contributed by Antonio Caputo, Annalisa Socievole, Floriano De Rango.

The dataset contains Bluetooth device proximity data collected by an
ad-hoc Android application called SocialBlueConn. This application was
used by 15 students at University of Calabria campus in Rende, Cosenza
(Italy) and logged both the internal contacts between the participants
and contacts with other 20 external mobile nodes. The dataset includes
the social profiles (Facebook friends and self-declared interests) of
the participants.
