A method for implementing a decentralized clustering mechanism includes: reserving, by a first wireless device located on a first channel, multiple first scheduled service periods from a first data transfer interval; switching, by the first wireless device, to a second channel within the first scheduled service periods, and transmitting a probe frame over the second channel, where the probe frame includes a cluster probe information element; reserving, by the first wireless device, multiple second scheduled service periods from a second data transfer interval according to timing information in the cluster probe information element; when a response frame from a second wireless device is received within the second scheduled service periods, identifying, by the first wireless device, whether an empty beacon scheduled service period exists; and if exists, transmitting, by the first wireless device, a beacon frame within the empty beacon scheduled service period.
