A Comparative Study on Energy-Efficient And Non Energy-Efficient Routing Protocols In Underwater Sensor Networks

Routing methods in underwater wireless sensor networks are subject to greater latency, more energy usage, little bandwidth, and insufficient efficiency when contrasted to terrestrial wireless sensor networks. Nowadays, it is used to discover life inside the ocean, and collect information about aquatic life and gather data for geographic variation. The sensor nodes operate within acoustic links to interact with one other, they vary from other networks. The efficiency of the information transfer to the destination is a critical factor because it consumes a lot of energy while transferring data. To overcome the aforementioned issues, an energy-efficient routing system is required, which increases the nodes or network lifespan. In this work, we analyze the different energy-efficient and non-energy-efficient UWSNs that are already available and classify them according to performance and efficiencies.
