Abstract: 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.

Abstract: Embodiments of the present invention provide a method for establishing an association between a STA and an AP, and the method includes: sending, by the STA, an association request frame to the AP, where the association request frame includes a service type element, and the service type element is used for indicating a sensor service type, an offloading service type, or a hybrid service type to which the STA belongs, where the sensor service type includes a first sensor service or a second sensor service, and the offloading service type includes a first offloading service or a second offloading service; and receiving, by the STA, an association response frame sent by the AP, where the association response frame is generated by the AP after determining, according to the service type element, a service type to which the STA belongs.
