Abstract

One of the fundamental differences between the terrestrial radio frequency (RF) signal and underwater acoustic signal is long propagation delay. This paper is focused on a scheduling scheme for regional data collection in under-water acoustic sensor networks. Long propagation delay of the acoustic signal causes a serious problem for transmission scheduling. In this paper, we propose an efficient transmission scheduling algorithm using the property of long propagation delay for real-time data collection which is critical to tactical surveillance applications. We show through the simulation that the proposed scheme reduces total transmission time and increases the network efficiency significantly.
