| Abstract: | The application and special requirements of time synchronization algorithm in wireless sensor network were introduced firstly. Then the un-synchronized reason, the relationship of local clock and logical clock, and the facts that impact the clock synchronizing precision were analyzed. Some promising methods deserving further study were proposed based on the classification of the existing clock synchronization algorithms. |
