According to the requirements of high synchronization precision among nodes and low communication costs,a new synchronization algorithm based on optimal linear fit has been studied.After analysis of FTSP algorithm,node classifying strategy was adopted to reduce the transition amounts of synchronization packet data,and parameter estimating theory of probability and statistics was then introduced to improve linear regression algorithm,reduce the influence of abnormal data to synchronization precision and extend node synchronization time.Experiments showed that this new algorithm can effectively reduce the synchronization costs and realize high synchronization precision with μs level errors.
