Abstract

A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.
