The sensor node is responsible for extract the valuable information from the bottom of the sea and explores that information with different applications like: mine reconnaissance, offshore exploration, disaster prevention assisted navigation and tactical surveillance. This study presents the several key aspects like generalized network model which focuses on the deployment of the sensor nodes, acoustic channel characteristics and underwater network metrics. This study also presents the methodologies used in hierarchical routing protocols based on architecture for underwater wireless sensor network. This research study also focuses the major issues with the hierarchical routing protocols. The well-defined evolution methods of this research study will help the researchers do further research in the field of routing protocols for underwater wireless sensor network.
