Prevailing Issues and Research Confront in Underwater Acoustic Sensor Networks

Abstract

The focal point of this paper examines a variety of approaches and the challenges in the design and the implementation on the research area of underwater acoustic sensor networks. Research in an Ocean is still unexplored boundary in this planet as compared to terrestrial sensor networks. This paper highlights various applications like oceanographic data collection, offshore exploration, underwater robotics, disaster prevention, pollution monitoring. This paper deals with main features of underwater sensor networks, deployment analysis in Two-Dimensional and Three-Dimensional architecture and components. Also focus on the research issues like limited bandwidth, restricted battery power, propagation delay, high cost, failure of sensors due to fouling and corrosions cross layer protocol stack design in UASNs.
