Abstract :
One of the fundamental differences between the terrestrial radio frequency (RF) signal and underwater acoustic signal is long propagation delay. This paper is contented with a MAC protocol for underwater sensor networks (USN) in which there are n sensor nodes in a transmission range W . Long propagation delay of the acoustic signal causes a serious problem for MAC protocol. If every sensor node has packet to transmit, there are n packets to be transmitted to the sink node. In this paper, we propose an efficient packet transmission scheduling algorithm for underwater acoustic communications with arbitrary values of n and W , using the property of long propagation delay.
