Abstract: Methods and a system described herein manage the power of IoTs and smart devices operating on a wireless network. When an access point coupled to the network receives a low power indication from a battery-powered IoT or smart device, it may take several actions in response. In one case, it extends the target wake time to become longer and longer to preserve the device's battery. In addition, the device changes its operation to conserve power. In another case, it provides power over the wireless network to the wireless device. The access point restores the target wake time when the device returns to a power-ok condition. The device resumes operation according to the parameters in effect before the low power condition occurs.
