In addition, when the internet of things access point detects that the current power consumption is larger than or equal to a second preset threshold value, the internet of things access point can request the wireless access controller to timely allocate the alternative reference internet of things access point so as to relieve the data processing pressure of the internet of things access point in the current wireless ad hoc network, avoid the situation that the data processing efficiency of the internet of things access point is influenced due to too high power consumption, and be beneficial to improving the stability of data transmission of the wireless ad hoc network.
