The existing wireless communication power control effect is poor. In order to control the wireless communication power effectively, this paper studies the effective control method of wireless communication power combined with adaptive algorithm. A control model of wireless communication network is established. On this basis, the signal-to-noise ratio of wireless communication with or without delay is calculated. Based on this, a simple power model is established. The adaptive algorithm is used to calculate the control parameters of the time-varying channel of wireless communication, the car model with system parameter identification is obtained, and the signal-to-noise ratio of mobile transmission signal is calculated. Under the influence of network transmission delay, a mathematical model is obtained which is in line with the actual communication environment, and the design of wireless communication power control method based on adaptive algorithm is realized. Comparing the absolute value of signal-to-noise ratio tracking error between this control method and two traditional methods, the larger the error, the worse the control effect. In the experiment, the absolute value of the control method under the adaptive algorithm is the smallest, and the speed to achieve the minimum error is the fastest. It can be seen that this method has the best control effect.
