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 - 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,
Proceedings of the IEEE Conference on Communications and Network
Security (CNS), October 2013.

new CRAWDAD dataset - round-trip time-of-flight measurements - May 29, 2014

A new dataset has been added to CRAWDAD.
cmu/supermarket

Round-trip Time-of-flight Measurements from a supermarket

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
magnetometer. At every location, 20 distinct readings were obtained
for RToF signatures as well magnetometer measurements, to capture the
variance, giving a total of 31780 readings.
