Communication technology, as an indispensable high-tech in public life and work, has great significance in controlling its information transmission. Aiming at the problem of high delay and packet loss rate existing in current research results of data transmission control in wireless communication network, a blocking troubleshooting method based on probability acceptance and discarding for the wireless communication network of marine buoy is proposed. BP neural network is used to detect the noise contaminated data and label it. The labeled noise data is reconstructed by inverse distance weighted interpolation method. According to the denoising of communication network, the process of congestion control is divided into two stages: congestion avoidance and congestion mitigation by introducing probability admission and discarding mechanism. When the caching resources are relatively sufficient, the node enters the congestion avoidance stage, and reduces the probability of congestion by probability admission of messages; otherwise, the node enters the congestion alleviation stage, and uses probability discarding of messages to alleviate or relieve congestion. The experimental results show that the proposed method is reliable and has lower delay and packet loss rate compared with the reference results.
