A time synchronization algorithm for underground linear WS

  • In view of characteristics of linear network structure used in coal mine underground and problem of bigger synchronization error of terminal node of linear network existed in traditional TPSN algorithm, a time synchronization algorithm of linear WSN based on clustering structure was put forward. The algorithm is based on traditional clustering algorithm, and uses clock drift compensation and abnormal data filtering technology to reduce network time synchronization error and balance energy loss of the entire network. The simulation result proves that the algorithm is correct.
