ABSTRACT:
A method of estimating a location of a wireless device providing a wireless attack. The method includes disposing a number of sniffers in a geographic region and receiving a number of wireless signals at one or more of the number of sniffers. The method also includes processing the number of wireless signals to identify a subset of the number of wireless signals that are associated with the wireless device and determining a number of received signal strengths associated with the subset of the number of wireless signals. The method further includes providing an estimation of the location of the wireless device utilizing the determined received signal strengths associated with the subset of the number of wireless signals.
