Abstract: A computing device can determine an estimated location of a target computing device based on historical signal readings describing wireless communication signals received from the target computing device. A signal reading can include data such as a signal strength value indicating the received signal strength of the wireless communication signal, a timestamp value and a geographic coordinate value indicating the location of a receiving computing device when the wireless communication signal was received. The signal readings can describe wireless communication signals received from the target computing device by one or more receiving computing devices and received during various times. The computing device can calculate the estimated location of the target computing device by triangulating the location of the target computing device based on the geographic coordinate value and signal strength value of three signal readings selected from the set of signal readings.
