The dartmouth/wardriving dataset (v. 2006-06-02)

Location-aware dataset for analyzing the errors in location estimates.


The authors collected the dataset through war driving, i.e., collecting Wi-Fi beacons by driving or walking around Dartmouth Campus, to understand the effect of using estimated AP locations.

collection environment 

"As researchers have started using data collected by war driving for applications such as localization, it is important to understand the errors in war-driving data. Given the actual AP locations on Dartmouth College campus, we performed war driving on the campus and obtained the estimated AP locations." [kim-wardriving]

"We believe that the Dartmouth college campus is an ideal place to perform this study. First, Dartmouth has wireless coverage almost everywhere on the campus. Second, all APs on the campus are centrally administrated. Thus, it is relatively straightforward to obtain information about these APs. Third, information about the location of APs is up-to-date since the college has recently replaced all of our APs and recorded detailed location data." [kim-wardriving]

network configuration: On Dartmouth campus, "all APs share the same SSID, allowing wireless clients to roam seamlessly between APs. On the other hand, a building's APs are connected to the building's existing subnet." [henderson-voice]

data collection methodology: 

"War driving is the process of collecting Wi-Fi beacons by driving or walking through a town, to discover and map the location of APs. Because war driving is easy and can be performed by anybody with a wireless card, a GPS receiver, and war-driving software, it is an effective way of collecting AP location information." [kim-wardriving]

sanitization: Every MAC address, non-Dartmouth SSID, and AP names have been anonymiazed.

This dataset contains the following traceset: placelab

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.
