Current State of Art techniques In Underwater Wireless Sensor Network

Abstract More than 70% of Earths surface is occupied by different kinds of water-bodies. Exploration of this vast unexplored aquatic environment has lead to the need of smart underwater communication techniques and therefore a lot of research is being carried out in this direction, lately. Underwater Sensor Networks are one of empowering technology majorly implemented for monitoring vast area of oceans to curtail unlawful activities and in preparing to combat harsh situations. They facilitate monitoring for various applications like ocean sampling network, submarine detection, disaster prevention, surveillance & protection of harbor & off-shore commercial facilities, border security, habitat & pollution monitoring, smuggling and in combating terrorism, etc. The paper presents the readers with an initial understanding of what underwater sensors are; their challenges and the current state of art techniques developed in this area.
