Abstract: A novel quick store-and-forwarding mechanism-based time synchronization method is proposed for strip-based Wireless Sensor Networks(WSNs). Combining store-and-forwarding mechanism with linear regression, this method achieves high accuracy and constant setup time. Experimental results show the method has micro second synchronization accuracy and constant synchronization setup time.

Key words: Wireless Sensor Networks(WSNs), time synchronization, strip-based, setup time
