Time synchronization is an important task in Wireless Sensor Networks (WSNs), because in most of the applications in WSNs need accurate time in nodes. A WSN consists of sensor nodes, which have the capability sense the data from its neighboring area and process the data and forward it to other sensor nodes. Underwater Wireless Sensor Network (UWSN) is a type of WSN, which is deployed in underwater. Time synchronization protocols have been introduced for WSNs, but none of them can be applied directly to UWSNs as most of these protocols do not consider the delay during propagation, limited band width, high error rate and mobility of nodes.
