new CRAWDAD dataset - wireless contacts traces from Android smartphones - October 30, 2016

A new dataset has been added to CRAWDAD.
upb/hyccups

Trace of wireless contacts, social connections, and user interests,
performed in an academic environment for 63 days, with 72 participants

Contributed by Radu I. Ciobanu, Ciprian Dobre.

Wireless contacts trace collected at the University Politehnica
of Bucharest in the spring of 2012, using an application entitled
HYCCUPS Tracer (http://hyccups.hpc.pub.ro), with the purpose of
collecting contextual data from Android smartphones. It was run
in the background and collected availability and mobile
interaction information such as usage statistics, user activity,
battery statistics, or sensor data, but it also gathered
information about a device's encounters with other nodes or with
wireless access points. Encounter collection was performed using
AllJoyn. The data was collected by constructing and deleting
wireless sessions using the AllJoyn framework based on
WiFi. Tracing was executed asynchronously. The duration of the
tracing experiment was 63 days, between March and May 2012, and
had 72 participants, out of which only 42 had at least one
contact. By analyzing the participants' Facebook profiles, the
social connections matrix was extracted, as well as the users'
interests. The trace (and others from the CRAWDAD collection) is
parsed within the MobEmu simulator (used in all UPB's papers),
publicly available at https://github.com/raduciobanu/mobemu.

If you use these data, please let us know, and you can use the DOI
10.15783/C7TG7K to cite. BibTeX and RIS are provided on the website.

new CRAWDAD dataset - Haggle traces converted for ONE simulator - August 30, 2016

A new dataset has been added to CRAWDAD.
uoi/haggle

Contributed by Dimitrios-Georgios Akestoridis.

This dataset contains seven connectivity traces that have been derived
from the cambridge/haggle/imote traceset (v. 2009-05-29). These
connectivity traces can be used for network simulations with the
Opportunistic Network Environment (ONE) simulator, since they are in
accordance with the syntax of the StandardEventsReader format. The
Python scripts that generated these connectivity traces are also
provided.

If you do use these data, please let us know, and you can use the DOI
10.15783/C7Z884 to do so. BibTeX and RIS are provided on the website.

Note #1: this dataset is derived from another dataset. We have trawled
the DataCite data archiving schema (http://schema.datacite.org/ for
those who are interested) and believe that everything is proper. So if
you have used CRAWDAD datasets to create other datasets (e.g.,
converted datasets into other formats, or derived encounter traces
from access point measurements, or combined datasets together), then
please get in touch as it would be good to share these with the
community.

Note #2: there is an electrical upgrade at Dartmouth this week so the
main crawdad server may be inaccessible. Try http://uk.crawdad.org/
if the main site doesn't work.

DOIs for CRAWDAD datasets - August 27, 2015

Hello CRAWDAD users,

It is now possible to cite datasets using DOIs (Digital Object
Identifiers). These increasingly popular persistent identifiers should
provide stable citation references for use in your papers when you use
CRAWDAD datasets. They should also help with anyone who is thinking of
contributing data to CRAWDAD, since some funding bodies now require
that datasets have DOIs.

So for instance you can now cite the latest version of the
dartmouth/campus dataset as follows:

David Kotz, Tristan Henderson, Ilya Abyzov, Jihwang Yeo, CRAWDAD
dataset dartmouth/campus (v. 2009‑09‑09), downloaded from
dartmouth/campus20090909, doi:10.15783/C7F59T, Sep
2009.

and you can access the dataset at both
dartmouth/campus20090909/>
and
http://doi.org/10.15783/C7F59T

We also now provide both BibTeX and RIS so that both LaTeX and Word
users can cite CRAWDAD datasets easily and accurately. If you are
interested in knowing some common data citation errors, and why it is
important to cite data correctly, then you might want to see the
article that we wrote for D-Lib Magazine
http://doi.org/10.1045/january2015-henderson
If you are interested in knowing more about DOIs then there is lots of
information at http://www.doi.org/

Cheers,
Tristan

PS it took a while for me to get my head around the issuing (or
"minting") of DOIs. So if you notice any weirdness then please shout.

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

A new dataset has been added to CRAWDAD.
icsi/netalyzr-android

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
fashion.

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

new CRAWDAD dataset - inter-arrival time measurements - June 10, 2014

A new dataset has been added to CRAWDAD.
gatech/fingerprinting

Fingerprinting of wireless devices exploiting information leaked due
to different device hardware compositions: Inter-Arrival-Time (IAT) of
packets from wireless devices

Contributed by A. Selcuk Uluagac.

In these datasets, we present the the inter-arrival time information
collected actively and passively from different wireless devices using
wire-side observations in a local network. The captures were collected
from 30 wireless devices including iPads, iPhones, Kindles,
Google-Phones, Netbooks, IP Printers, IP Cameras, etc., from various
applications and protocols such as Skype, ICMP, SCP, Iperf. Due to
heterogeneity in devices (e.g., deterministic hardware and software
configurations), time-variant behavior of network traffic stemming
from different devices can be used to create unique, reproducible
device and device type signatures and to fingerprint devices and their
types as explained in A. Selcuk Uluagac, Sakthi V. Radhakrishnan,
Cherita Corbett, Antony Baca, and Raheem A. Beyah, A Passive Technique
for Fingerprinting Wireless Devices with Wired-side Observations,

Contributed by Aveek Purohit, Shijia Pan, Kaifei Chen, Zheng Sun, Pei Zhang.

The dataset is meant to aid development and evaluation of indoor
location in complex indoor environments using round-trip
time-of-flight (RToF) and magnetometer measurements. The dataset
provides Round-trip time-of-flight (RToF) and magnetometer
measurements at 1589 mobile node locations from 30 deployed stationary
anchors in the 26m x 24m New Wing Yuan supermarket in Sunnyvale, CA.
The data was collected during working hours over a period of 15 days.
The nodes are equipped with chirp spread spectrum Nanotron nanoLoc
radios (802.15.4a) and a Honeywell's HMC5843, a 3-axis digital

CRAWDAD workshop summary - November 07, 2005

The CRAWDAD workshop at Mobicom 2005 was a great success.

Wireless network researchers are seriously starved for data about how
real users, applications, and devices use real networks under real
network conditions. CRAWDAD (Community Resource for Archiving
Wireless Data at Dartmouth) is a new National Science
Foundation-funded project to build a wireless-network data archive
for the research community. It will host wireless data and provide
tools and documents to make collecting and using the data easy. This
resource should help researchers identify and evaluate real and
interesting problems in mobile and pervasive computing. To learn more
about CRAWDAD and discuss its direction, about 30 interested people
gathered at a workshop held in conjunction with MobiCom 2005.

We published a more complete summary in IEEE Pervasive Computing magazine:
http://doi.ieeecomputersociety.org/10.1109/MPRV.2005.75
