Energy Efficient Underwater Wireless Acoustic Sensor Networks: A Review
During last two decades, underwater acoustic sensor networks (UwASNs) are widely being deployed undersea to sense the environmental variations and objects for security use. Unlike the wireless sensor networks, UwASNs use acoustic channel for the communication. Limited battery-driven sensors compelled to develop the energy efficient UwASNs for the continuous operation of monitoring. Therefore, this paper reviews the energy efficient UwASNs exist in the literature.
