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.
