In order to improve the data transmission efficiency of wireless network data transmission,an adaptive congestion con-trol method for wireless network data transmission is proposed.Based on the conversion relationship in the congestion control stage,the data transmission window size of wireless network is adaptively adjusted to realize the control of data transmission flow in the process of congestion control.Constructing the topology of wireless network,taking the transmission delay as the constraint,determi-ning the threshold of node traffic backlog through the data transmission rate,and determining the degree of node congestion;Estimate the congestion degree of each path of wireless network data transmission,and select the path with the highest transmission rate as the optimal data transmission path.The experimental results show that after the application of the proposed method,the throughput of wireless network data transmission can be increased by 85%,the node mortality can be controlled below 20%,and the fairness of con-gestion control can be improved by 120%.
