Original Abstract Submitted
a method is provided that is performed in a wireless network to detect a rogue wireless device. the method comprises detecting a suspect wireless device in the wireless network based on messages transmitted by the suspect wireless device using a first media access control (mac) address that is also used by a valid wireless device in the wireless network. when a suspect wireless device is detected, the method next includes sending to the valid wireless device in the wireless network a request configured to cause the valid wireless device to change its mac address. after the valid wireless device has changed its mac address, the method involves observing messages transmitted by the suspect wireless device in the wireless network. the method then includes determining that the suspect wireless device is a rogue device when the suspect wireless device continues to transmit messages using the first mac address.
