In distributed network systems the time synchronization plays a critical role. This time synchronization is investigated in the underwater sensor networks. The protocols used in the existing system do not consider long propagation delays and sensor node mobility. Their proposed system introduces the STSL (Synchronized Time Synchronized Location) algorithm which provides the accurate result. This approach is the use of relative speed and direction information available at the mobile UL node to compensate for node mobility. The STSL algorithm uses a two-step approach, in which first nodes are time-synchronized and then location is estimated.
