Abstract :
In this paper, a time synchronization method for underwater wireless sensor networks (UWSN), UA-TSP, is presented. The proposed method not only compensates the main time delay in acoustic communication, but also decreases the cumulate errors in the multi-hop scene through a loop convergence method. The implementation of UA-TSP is combined with the nodes discovering process, and less control frame is exchanged. The simulations and experiments results show that the method can reach a satisfactory tradeoff among the time synchronization precision, communication efficiency and power consumption.
