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.

Please note:

We have recently made changes to the crawdad.org website that affect ALL current users. The website has been physically moved to a new server, and we have made changes to our user registration process. Together, these changes require ALL previous users to re-register.

This email was recently sent to all current CRAWDAD users.

Please contact us if you experience any problems.

CRAWDAD is grateful to its current and past sponsors.

New CRAWDAD Data Set - Measurements for PhD: Surface density of radiation energy as an integral measure for the characterization of exposure to electromagnetic emissions - August 6, 2019

A new data set has been added to CRAWDAD:

ues/emespy

The measurement results provided here are part of work on PhD thesis connected with measurement results variability reduction (main focus was on GSM/UMTS system

Contributed by Darko S. Suka, Predrag V. Pejovic, Mirjana I. Simic-Pejovic

Equipment used is the dosimeter (or exposimeter) EME Spy 140 (manufactured by Satimo). Similar to the procedure described in (Vermeeren, 2013; Markakis et al., 2013), the exposimeter was placed at available position in the investigated rooms and were standing alone. It was, thus, not worn by adults. Also, no influence due to shielding occured, like when exposimeters are carried on the body (where underestimations up to 6.5 dB are possible according to Iskra et al. (2010)). During measurement period, all location were secured, and only authorized technical personnel that performed measurements had access to such places in order to provide measurement conditions of unperturbed field, according to EN 50492:2010 and EN 50413:2010

New CRAWDAD Data Set - Data concerning social interaction and propinquity based on wireless and bluetooth. - March 10, 2017

A new data set has been added to CRAWDAD:

copelabs/usense 2017-01-27

Data concerning social interaction and propinquity based on wireless and bluetooth.

Contributed by S. Firdose, L. Lopes, W. Moreira, R. Sofia, P. Mendes.

This dataset comprises experiments carried out with the open-source middleware NSense (fomerly named as USense), available at https://github.com/COPELABS-SITI/NSense. The data has been collected based on four sensors: bluetooth; Wi-Fi; microphone; accelerometer. NSense then relies on four different pipelines to compute aspects such as relative distance (Wi-Fi); social strength (based on bluetooth contact duration); sound activity level; motion. We set up experiments making use of Samsung Galaxy S3 devices. For each experiment, there is the following set of data files: - SocialProximity.dat has three columns: Timestamp, DeviceName, Encounter Duration, Average Encounter Duration, Social Strength (Per hour) and Social Strength(Per minute) towards DeviceName - DistanceOutput.dat has three columns: Timestamp, DeviceName, and Distance towards DeviceName - Microphone.dat has two columns: Timestamp, and Soundlevel(QUIET, NORMAL, ALERT and NOISY) - PhysicalActivity.dat has two columns: Timestamp, and Activity as STATIONARY, WALKING and RUNNING There are two tracesets. A first traceset has been collected relying on a first NSense version in 2015. Then, a second traceset has been collected in 2016, with a refined version of NSense. In all tracesets, devices have been carried around by people that share the same affiliation during their individual daily routines (24 hour periods).

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

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

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.
