Localization with Dive'N'Rise (DNR) beacons for underwater acoustic sensor networks

In this paper, we address the localization issue in Underwater Sensor Networks (UWSNs). We propose Dive'N'Rise(DNR) Positioning, the novel idea of using DNR beacons for localization. These beacons get their coordinates from GPS while floating above the water, then they dive into water. While sinking and rising, they broadcast their positions. Sensor nodes are localized by passively listening to DNR beacon messages which reduces the communication cost and the energy consumption. We analyze localization success and error for static and mobile UWSNs.
