1. A method, comprising:
receiving, at a first wireless AP of a first BSS and from a second wireless AP of a second BSS, data indicative of an 802.11-based TWT schedule of one or more clients of the second BSS;
determining, by the first wireless AP and based on the data indicative of the 802.11-based TWT schedule of the one or more clients of the second BSS, a TWT service schedule that defines TWT windows during which the first wireless AP provides services to the one or more clients of the second BSS;
identifying, by the first wireless AP, an IoT device among the one or more clients of the second BSS; and
servicing, by the first wireless AP and based on the TWT service schedule, the IoT device of the second BSS by impersonating a BSS identifier (BSSID) of the IoT device of the second BSS during at least one off-channel period of the first wireless AP,
wherein the first wireless AP services the IoT device of the second BSS at a time when the second wireless AP is unable to service the IoT device of the second BSS.
