Abstract
Dataset for evaluation of co-presence detection
We conducted a study with 126 subjects, over three months, collecting data from various sensors, that resulted in a multimodal dataset for co-presence detection. We publish a subset of the original data set in the period between 01.06.2018 and 15.06.2018 including Wi-Fi scans as proximity verification set, magnetometer as sensor data, the positions of Wi-Fi access points, and magnetometer's sensor hardware.
This study has been published at IEEE PerCrowd 2020, M. Haus, A. Y. Ding, J. Ott, "Multimodal Co-Presence Detection with Varying Spatio-Temporal Granularity", in Proceedings of IEEE 3rd International Workshop on Context-awareness for Multi-device Pervasive and Mobile Computing (PerCrowd), 2020.

Traceset
tum/proximityness/traceset1
- file: proximity_verification_set_wifi.csv.gz
- description: proximity_verification_set_wifi.csv.gz contains the scans of Wi-Fi access points including mobile device's id, relative time, and BSSID. We have anonymized the device id and BSSID with substitute identifier. In addition, we converted the absolute timestamp to a relative time using a time reference point.
- measurement purpose: ARRAY(0x55bfb7a81de0)

trace1: first trace
tum/proximityness/traceset2
- file: proximity_verification_set_wifi_positions.csv.gz
- description: proximity_verification_set_wifi_positions.csv.gz contains the positions of Wi-Fi access points including BBSID and relative position. We have anonymized the BSSID and coordinates of Wi-Fi access points with substitute identifier.

tum/proximityness/traceset3
- file: sensor_data_magnetometer.csv.gz
- description: sensor_data_magnetometer.csv.gz contains the magnetometer's sensor data including mobile device's id, relative time, and x, y, z of magnetometer sensor. We have anonymized the device id with substitute identifier and converted the absolute timestamp to a relative time using a time reference point.

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.
