Review on Intend Adaptive Algorithms for Time Critical Applications in Underwater Wireless Sensor Auditory and Multipath Network

In the present scenario underwater wireless sensor network (UWSN) is a serious area for the research because there are many challenges still remain to be solved. UWSNs have self-powered sensor nodes and some autonomous vehicles are installed underwater, which implement associative task using acoustic link. It's becoming popular everyday due to their indispensable role in different application like pollution monitoring, ocean mapping, oil and mineral exploration, disaster prevention (like tsunami) and assisted navigation & tracking. In this paper, we analyze the basic concept of underwater sensor network, communication process, literature survey, different architecture of two dimensional and three dimensional and we also discuss the challenges and applications of UWSNs.
