The buffalo/phonelab-wifi dataset (v. 2016-03-09)
Wifi scan results and connection status collected using the PhoneLab smartphone testbed.
Contributed by Jinghao Shi, Chunming Qiao, Dimitrios Koutsonikolas, Geoffrey Challen.
Smartphones perform Wifi scans to adapt to the changing wireless environments causes by mobility. From network monitoring perspective, such scans provide a natural stream of network measurements from client's point of view. In order to see whether such measurements can provide new insights in monitoring large scale wireless networks, we collected the Wifi scan results data, together with other Wifi related logs, from the PhoneLab smartphone testbed over 5 months. All data are collected passively from the smartphones.

- collection environment
-
PhoneLab is a large scale smartphone testbed at University at Buffalo (UB). Participants carry instrumented Nexus 5 smartphones as their primary device. We instrument the PhoneLab platform to collected Wifi related events. During the course of our experiment, Wifi data of 284 devices were reported.
- network configuration
-
The dataset contains the Wifi scan results reported by each smartphones. Given that PhoneLab participants are primarily UB faculty, staff and students, we expect most of the Wifi networks reported to be UB campus Wifi network or each participants' home Wifi network.
- data collection methodology
-
Android system sends broadcasts when certain events happen, such as Wifi scan results available, Wifi connection status changed, etc. We passively log such events when they occur.
- sanitization
-
All identifiers that appear in our dataset, including the device ID, AP SSID and BSSID, have been hashed. These identifiers are hashed consistently throughout the dataset, so the same identifier can be found in each traceset. We also provide unhashed OUIs to allow analysis of particular manufacturers' devices.
- limitation
-
Since we only passively listen for the Wifi scan result events, the temporal resolution solely depend on the internal scan frequency of Android system.
This dataset contains the following traceset:
wifi
Wifi scan result and other Wifi related events.
