The embodiment of the invention provides a wireless network power control method and system based on the Internet of Things. An STA receives power control information broadcasted by the AP in the IoT channel, and the power control information is broadcasted and sent by the AP in the IoT channel according to the configuration of the network management module; and the STA adjusts the wireless signal transmitting power according to the power control information and a preset power control decision. When the STA moves between different power level areas, the STA can be switched to different power level areas. The STA receives power control information broadcasted by APs located in different power level areas in the IoT channel, therefore, the STA can judge whether the STA is located at the center position or the edge position of the power level area according to the received power control information; the wireless signal transmitting power is adjusted before the wireless signal transmitting power is accessed to th
