The most important service provided by distributed networks is \"Time synchronization\" for terrestrial Wireless Sensor Networks (WSNs). Several time synchronization protocols have been proposed. Factors like long propagation delays which are used for acoustic communication and sensor node mobility were not considered in several proposed protocols. For UWSNs, \"Time synchronization solution\" is specifically designed. \"Mobi-Sync\" a time synchronization scheme is proposed for mobile under water sensor networks. Mobi-Sync takes into consideration of spatial correlation among the mobility patterns of neighboring UWSNs. This enables Mobi-Sync to accurately estimate the long dynamic propagation delays.
