This paper proposes and evaluates a new time synchronization protocol called Hierarchical Time Synchronization Protocol(HTSP) which is an advanced version of the Flooding Time Synchronization Protocol(FTSP).The concept of hierarchy is adopted,and the hierarchy concept is used in collecting statistics for the number of child nodes of each node.With the collected number of child nodes,the HTSP can reduce the number of packet transmission.Simulation results show the energy consumption of the HTSP is only 74% of that of the FTSP.
