Over the recent years, the Synchronization challenges in wireless sensors networks has been a hot topic and continues to be as an active research area in the last few years. However its importance is shown in the way to better organizing the sensors into the network, to communicate with each other via radio links for sharing and Treatment of reliable information. The main topic in this paper, we propose an improvement over Timing-Sync for sensor Networks (TPSN) to synchronize nodes in a wireless sensors network more effectively, with a good precision and lower missed messages. The simulation result using ns-2.34 shows that this protocol has better synchronization accuracy and low missed messages as compare to TPSN.
