METHOD AND APPARATUS FOR IMPLEMENTING DECENTRALIZED CLUSTERING MECHANISM

摘要

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.

1. A method for implementing a decentralized clustering mechanism, wherein the method comprises:
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, the first wireless device to a second channel within the first scheduled service periods, and transmitting a probe frame over the second channel, wherein the probe frame comprises a cluster probe information element, and the cluster probe information element comprises timing information that is used for enabling a second wireless device located on the second channel to transmit a response frame in response to the probe frame; reserving, by the first wireless device, multiple second scheduled service periods corresponding to the first scheduled service periods from a second data transfer interval according to the timing information comprised in the cluster probe information element; when the response frame transmitted by the second wireless device is received within the second scheduled service periods, identifying, by the first wireless device by using an extended cluster report information element comprised in the response frame, whether an empty beacon scheduled service period Beacon SP exists; and if the empty Beacon SP exists, transmitting, by the first wireless device, a beacon frame within the empty Beacon SP, so that the first wireless device joins a decentralized cluster in which the second wireless device is located.
