Review on Underwater Sensor Networks: Applications, Research Challenges and Time Synchronization

Abstract

Earth is covered with 70% of water that could be river and ocean also. The underwater sensor network technology become more and more popular for monitoring oceans. This paper is a literature review of underwater sensor network, different architectures for two-dimensional and three-dimensional underwater. We are highlighting main applications and challenges of underwater sensor networks and the need of time synchronization schemes for Underwater Sensor Networks.
