Wireless Networking

These datasets are part of Community Resource for Archiving Wireless Data (CRAWDAD). CRAWDAD began in 2004 at Dartmouth College as a place to share wireless network data with the research community. Its purpose was to enable access to data from real networks and real mobile users at a time when collecting such data was challenging and expensive. The archive has continued to grow since its inception, and starting in summer 2022 is being housed on IEEE DataPort.

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


Dataset of all visible APs of 13 hotspot locations in Seattle, WA over one week.

We measured the performance and application support of all visible APs at 13 hotspot locations around University Avenue, Seattle, WA, near the University of Washington over the course of 1 week.

Channel energy levels from Wi-Fi networks as seen from a 802.15.4 radio.

We use a sensor network composed of TelosB motes deployed in the library building to collect RF energy level samples (RSSI) on all 802.15.4 channels in the 2.4 GHz ISM Band. The building has several collocated Wi-Fi networks in normal operation. These networks produce interference for the 802.15.4 radios. Sensor nodes record RSSI values every 20 us, simultaneously on all channels, for 130 ms and then write the result to the respective files. This process is repeated every 8 seconds for around 4h.


Traces of network activity at OSDI 2006.

The authors gathered a detailed trace of network activity at OSDI 2006 to enable analysis of the behavior of a wireless LAN that is (presumably) heavily used.

It is a large-scale data set of wireless network coverage for over 22,000 4G base stations in France. This data set is generated by applying VoronoiBoost and official sources of base station deployment. The data covers ten main metropolitan areas in the country, encompassing a variety of dense urban, suburban and rural areas.


VPN session, DHCP log, and trap log data from wireless network at USC.

This dataset includes VPN session, DHCP log, and tcap log data, for 79 access points and several thousand users at USC.

date/time of measurement start: 2003-12-23

date/time of measurement end: 2006-04-28

collection environment: This data set was collected during 2003-2005 at the USC campus, where the number of WLAN users was over 4500.


Adyton: A Network Simulator for Opportunistic Networks

Adyton is an event-driven network simulator, written in C++, for Opportunistic Networks (a.k.a. Delay-Tolerant Networks) that is capable of processing contact traces. The Adyton simulator supports a plethora of routing protocols and real-world contact traces, while also providing several congestion control mechanisms and buffer management policies.


Outdoor temperature data collected by taxis in Rome, Italy.

This dataset is to be used in conjunction with the roma/taxi dataset and provides the outdoor temperature of the areas in Rome where the taxis were located (289 taxicabs over 4 days).

This dataset contains traces of 802.11p packets, collected in a rural area located in the periphery of Aachen (Germany) in 2012, with the presence of an RF jamming signal with constant, periodic, and reactive jamming patterns.

This dataset contains several tracesets of 802.11p communications with the presence of an RF jamming signal. The RF jammer has different patterns of operation, namely constant, periodic, and reactive jamming. The observations were performed in a rural area located in the periphery of Aachen in Germany.


This dataset contains traces of 802.11p packets, collected in an anechoic chamber and outdoors in Porto (Portugal) in 2011, with and without the presence of an RF jamming signal with constant, reactive, and pilot jamming patterns.
