Abstract

The Ocean remains the least explored frontiers. Many oceanic and marine applications seen relatively slow in exploiting the state of the art info-communication technologies. Acoustic communications is the most promising mode of communication underwater. Because of high error rate and long propagation delay of the acoustic channel, it is difficult to provide energy efficient communication. We proposed a new scheme which guarantees a good balance between the overall energy efficiency, end-to-end packet delay and end-to-end delivery ratio. This scheme smartly combines power-control with multipath routing and packet combining at destination. With carefully designed power-control strategies and since no hop-by-hop retransmission is allowed, multipath transmission introduces much shorter delay than the traditional one-path scheme with retransmission. We conducted extensive simulations to evaluate the performance of multipath power-control transmission. Our result shows that multipath transmission is highly energy-efficient with low end-to-end packet delays.
