Algorithms for power-efficient data acquisition in underwater sensor networks

Approaches that have already been developed for terrestrial sensor networks cannot be used for Underwater Sensor Networks (UWSN) because of certain features of acoustic communication [2,3]. Therefore, we propose an architecture for UWSN that aims to deliver the information from under water to the surface and then to the control center from there. We formulate the mechanism using a grid pattern of local sinks on the sea surface and randomly moving sensors, forming a wireless underwater ad-hoc network under the sea surface. This design concentrates on the reception of information. Although reliability is achieved through the redundancy of data, our work is aimed at controlling the congestion as well. The mechanism has been made self-adjusting so as to achieve robustness. A solution for the important problem of power management has also been proposed. The primary goal of this system is to make oil discovery process under water easier.
