Abstract :
A reliable time synchronization protocol is essential for distributed Wireless Sensor Networks. A design of High-precision Time Synchronization Protocol (HTSP) is proposed in this paper based on the Flooding Time Synchronization Protocol (FTSP). The HTSP adjusts the clock offset between nodes and improves abnormal condition treatment to achieve stable time synchronization. We validate HTSP through the platform of TelosB and we can achieve more accurate and stability than conventional mechanism.
