This paper proposes a multichannel MAC protocol in underwater acoustic sensor networks for transmitting monitoring data. Since the transmission speed of acoustic wave is much slower than terrestrial, the propagation delay in the water is much more also. Moreover, due to the long propagation delay, the hidden terminal problems are more severe. For solving the long propagation delay and hidden terminal...
This paper proposes a MAC protocol for enhancing the throughput in underwater acoustic sensor networks. Since the transmission speed of acoustic wave is much slower than that of radio, the propagation delay in the water is much longer. For solving the long propagation delay and hidden terminal problems, the throughput may become very low. To improve the throughput, this paper proposes an algorithm...
