Abstract :
Time synchronization is a critical service for distributed networks. In this paper, we investigate this problem in underwater sensor networks (UWSNs). We propose a novel time synchronization scheme, called ``Mobi-Sync´´. Mobi-Sync effectively utilizes the spatial correlation of underwater mobile sensor nodes to estimate the long and dynamic propagation delays. Simulation results show that Mobi-Sync outperforms existing schemes in both accuracy and energy efficiency.
