Wireless Sensor Network Protocols in Underwater Communication

Ocean expeditions can use underwater wireless sensor networks (UWSNs) for a variety of purposes, which facilitates with the extraction of previously undiscovered data. But despite recent developments in wireless sensor networks and their widespread use in contemporary research and economic development, the aquatic environment has largely remained unscathed. Therefore, sensors are being placed underwater in order to identify these activities. These sensors must be compact and use little energy. In this study, many procedures are carried out and applications are presented. Underwater wireless sensor networks are used in the military for surveillance, disaster monitoring, and prospecting undersea resources. When these sensors are in use, data is transmitted in three different ways: acoustically, radio frequency, and optically. The four primary forms of architecture are 1D, 2D, 3D, and 4D, and they serve as the foundation for developing UWSN applications. Several challenges are encountered as these sensors are being installed. In this work, these difficulties are briefly discussed. Three basic classifications of routing protocols—localization-based, localization-free, and cooperative routing schemes—are used to classify several widely used routing protocols. Further study included is the subject of routing-related concerns for underwater wireless sensor networks.
