About the research work -  

From the scientific, military and commercial point of view, a continuous real-time, effective and synoptic sampling of ocean has gained huge importance. From the necessity of various possible applications such as ocean environmental monitoring, undersea exploration, seismic monitoring, assisted navigation, tactical surveillance and so on, a new technology of Underwater Acoustic Sensor Network (UASN) has been developed. UASN can be considered as a conglomeration of underwater acoustic wireless communication and Wireless Sensor Network (WSN). 


In this research work, a problem of designing three-dimensional UASN has been considered. An energy efficient cross-layer protocol stack has been developed for this three dimensional network. The proposed cross-layer protocol stack encompasses the important functionalities of physical layer, data link layer, network layer, transport layer as well as application layer. Also, various protocols of network management planes such as time synchronization, Cluster-Head selection and power level management has been incorporated.

Various simulation tools have been explored for demonstrating the proposed protocol stack. For testing the protocol stack on hardware testbed, an indoor laboratory based hardware testbed set-up has been developed in this work. Proposed protocol stack has been successfully implemented on this testbed set-up.
