Aiming at the large error of keeping time between communication nodes in wireless communication networks, we propose a twoway time synchronization algorithm based on timingsync protocol for sensor network  (TPSN). We design a miniaturized and modular highprecision time synchronization system which can be used in frequency hopping synchronization and time slot synchronization under the TDMA network architecture. Firstly, we set the node which has not received any call within 10 seconds as the host. Secondly, the host responds to only one slave within 1 second. Finally, the synchronization error between nodes is calculated by recording the sending time of masterslave node, deducting or compensating the  logic processing delay, RF transmission delay, and the frequency difference between the two ends of the calibration. Simulations under different conditions show that the synchronization error between nodes can be as accurate as about 30 nanoseconds. This indicates that the solution's time synchronization accuracy is high, and the error is small, thus it can meet the needs of tactical objectives such as collaborative detection, collaborative attacks and collaborative jamming between nodes in the wireless communication network.
