    In our earth 75% covered by water that could be river and ocean also. The underwater sensor network are enabling technology and become more and more popular for monitoring vast area of oceans. Underwater sensor Networks consist of a variable number of sensors that are deployed to perform monitoring tasks over a given area. The UWSNs provide continuous monitoring for various applications like ocean sampling network, pollution monitoring, submarine detection, disaster prevention, etc. In this paper, we discuss the internal architecture of underwater sensor, we discussed the literature of underwater sensor network, different architectures for two-dimensional and three-dimensional underwater sensor networks are discussed, and we also discussed the application and main problem or issue in underwater sensor network

    In this paper is a concept of  a technique of sending and receiving message below water. There are several ways of employing such communication but the most common is using hydrophones. Under water communication is difficult due to factors like multi-path propagation, time variations of the channel, small available bandwidth and strong signal attenuation, especially over long ranges. In underwater communication there are low data rates compared to terrestrial communication, since underwater communication uses acoustic waves instead of electromagnetic waves.  we present a novel platform for underwater sensor  networks to  be used  for long-term monitoring of coral reefs  and  fisheries.    The  sensor  network consists  of static and  mobile  underwater sensor  nodes.   The  nodes  communicate  point-to-point using  a novel high-speed optical  communication system  integrated into  the  TinyOS stack,   and they  broadcast using an acoustic  protocol  integrated in the TinyOS stack.    The  nodes  have  a variety of sensing  capabilities,   including cameras,  water   temperature,  and  pres- sure.    The  mobile  nodes  can  locate  and  hover  above  the static nodes for data mining  and  they  can perform  network maintenance functions such  as deployment, relocation, and recovery.   In this  paper  we describe  the  hardware and  soft- ware  architecture of this  underwater sensor  network.   We then  describe  the  optical  and  acoustic  networking protocols and  present  experimental networking and  data collected  in a pool, in rivers,  and  in the  ocean.  Finally, we describe  our experiments with  mobility for data mining  in this  network.

    In recent year wireless sensor network has been an emerging technology and promising technology in unveiling the riddle of the marine life and other underwater applications. As it is a permutation of computation, sensing and communication. In the 70% of the earth a huge amount of unexploited resources lies covered by oceans. To coordinate interact and share information among themselves to carry out sensing and monitoring function underwater sensor network consists number of various sensors and autonomous underwater vehicles deployed underwater. The two most fundamental problems in underwater sensor network are sensing coverage and network connectivity. The coverage problem reflects how well a sensor network is tracked or monitored by sensors. An underwater wireless sensor networks is the emerging field that is having the challenges in each field such as the deployment of nodes, routing, floating movement of sensors etc. This paper is concerned about the underwater acoustic wireless sensor network of routing protocol applications and UW-ASNs deployments for monitoring and control of underwater domains

    The oceans alone cover almost three quarters (71%) of our planet and along with rivers and lakes are critical to our well-being. They must be continuously observed to detect climate changes or pollution of the environment which effects human and animal habitat, especially in this 21st century which global warming is the main issue. Recently, sensor networks have appeared as an important technique for many applications, including monitoring, measurement, surveillance and control. The idea of applying sensor networks for underwater monitoring has become more interests. In this thesis, the development of an underwater sensor that able to perform monitoring applications is described. The systems and technologies of underwater sensor network has been carried out and investigated for a better understanding. Few possible solutions of designing the system are discussed and a more suitable solution for real time monitoring is proposed. By the development of the proposed underwater sensor network monitoring system, any changing on the water quality should be able to monitor instantly by the end user, which consists of related research group or organization and society
