N2 - Time synchronization is an essential service in many sensor network applications. Several time synchronization protocols have been proposed to synchronize the clocks on sensor nodes. All the synchronization protocols bring energy and complexity overhead to the network. There are many WSN applications which timestamp their samples with second level granularity. We claim real-time clocks can satisfy timing requirements of such applications. In this work, real time clocks are utilized to build a time-synchronized sensor network. We propose an accurate, robust, scalable and energy efficient approach to synchronize sensor network by accurately initializing RTCs on sensor nodes. Our experiments show that accurate initialization of real time clocks allows us to build a time-synchronized sensor network without any energy or complexity overhead of running sophisticated online time synchronization protocol.
