Abstract :
Time synchronization and energy saving are important for sleeping-based media access control protocols in wireless sensor networks. Existing time synchronization methods were not designed for energy-efficient and sleeping based MAC protocol in WSN in mind. We proposed the energy-efficient clustering time synchronization algorithm by introduce synchronization schedule adopting and border node controlling to the synchronization algorithm. Our solution features minimal energy cost on synchronization. It also provides latency reduce. Some simulation experiments are done to evaluate the performance of the proposed approach.
