- Abstract:
- Time synchronization is an important part of distributed applications over a sensor network. In this work we investigate time synchronization problems over a shallow UWSN, taking into account all main communication challenges of the water channel and observing its behavior in simulation and real tests. It is proposed an hybrid frame based time synchronization using both, LFM and OFDM communication with channel impulse response equalization. Simulation results show how Hybrid synchronization outperforms existing synchronization protocols and how these results are affected in real water tests.
