Node grouping method, node, and access point

摘要

Embodiments of the present invention provide a node grouping method, a node, and an access point (AP). The method comprises: receiving a grouping request sent by an AP; according to the grouping request, obtaining a received signal strength indicator (RSSI); obtaining a group Identity (ID) of a group determined according to the RSSI. In the embodiment of the present invention, nodes are grouped according to the RSSI, so as to solve the problems of contention collision and low network performance in a large-scale network, avoid the problem of unfair throughput incurred by the near-far effect, and reduce the phenomena of hidden terminals.

1. A method for grouping a node, comprising:
receiving a group joining request sent from a first node; sending a first grouping poll to each node in a first set of nodes based on the group joining request, wherein the first set of nodes is composed of a grouped node in nodes served by an Access point (AP); receiving a first grouping acknowledgement sent from each node in a second set of nodes, wherein the second set of nodes is composed of a node that monitors the group joining request in the first set of nodes; receiving a two-way neighbor node list sent from the first node, wherein the two-way neighbor node list comprises a third set of nodes, and the third set of nodes is composed of a node corresponding to the first grouping acknowledgement monitored by the first node; and grouping the first node based on the two-way neighbor node list.
