1. A method comprising:

  • binding a predetermined access control role for Internet of Things (IoT) devices to a Service Set Identification (SSID) for a Access Point (AP) in a wireless network;

    upon a condition causing a plurality of devices to attempt to associate with the AP, assigning, with the AP, a first value for an Authentication Control Threshold (ACT) field in a first advertisement packet to allow the IoT devices having the predetermined access control role to immediately attempt to associate with the AP, the first value being a maximum value for the ACT field;

    transmitting, with the AP, the first advertisement packet including the first value for the ACT field for association of IoT devices having the predetermined access control role;

    receiving authentication requests from one or more IoT devices in response to the first advertisement packet and associating the one or more IoT devices with the AP;

    assigning, with the AP, a second value between a minimum value and a maximum value to an ACT field in a second advertisement packet for one or more devices having an access control role other than the predetermined access control role for IoT devices;

    transmitting, with the AP, the second advertisement packet including the second value for the ACT field for one or more devices having an access control role other than the predetermined access control role allowing one or more devices having an access control role other than the predetermined access control role to attempt association with the AP within a random time in a given time window; and

    receiving authentication requests from one or more devices in response to the second advertisement packet and associating the one or more devices with the AP.
