Abstract:
The need for underwater communications exists in the areas of pollution monitoring, ocean sampling networks, tactical surveillance applications, exploration of natural undersea resources, mine reconnaissance and predicting wave tides. Deployment of underwater sensor networks for real-time investigation is the major challenge. There is a need to deploy underwater networks that will enable real-time monitoring of selected ocean areas, remote configuration and interaction with onshore human operators. This can be obtained by connecting underwater instruments by means of wireless links based on acoustic communication is the most versatile physical link for continuous wireless sensor networks in underwater scenarios. In this paper large-scale underwater Sensor Networks (UWSN) and Underwater Ad-hoc Networks (UANETs) using Solar-Powered Autonomous Underwater Vehicles (SAUV) to explore the oceanic environment is proposed. Kong Wobbler base station with acoustic communication devices is considered, which locates the pre-deployed underwater sensor modules through acoustic communication. The sensor modules are installed with various acoustic sensors and video capturing devices to study the underwater resources as well as for surveillance needs for predicting the environmental conditions highlighting potential applications of seismic monitoring that provides a better disaster warning mechanism. The simulation results are encouraging as this approach is extremely helpful in surveillance; intruders are tracked and real-time data streaming is processed.
