In underwater sensor networks (UWSNs), information transmission is extremely challenging because of the underwater channel. Underwater acoustic channel suffers from long propagation delay and low bandwidth is inclined to packet losses. Hence, the design of an energy efficient communication system is challenging under the water. In this paper, we present an energy efficient clustered multi-hop routing...
