A SURVEY ON UNDERWATER SENSOR NETWORKS

Wireless sensor networks (WSN) behave as a digital skin, providing a virtual layer where the information about the physical world can be accessed by any computational system. 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 pollution monitoring, submarine detection, disaster prevention etc. In this paper discuss an invaluable resource for realizing the vision of the Internet of Things (IoT). we will focus on the issues that take place at the network level and applications and challenges of underwater sensor, we also discuss the main problem or issue in underwater sensor network.
