  • Abstract In the current underwater acoustic sensor network, the sensor is located in the deep sea and has the disadvantages of being easily damaged and difficult to replace the battery. Therefore, this paper proposes a triangular topology in the underwater acoustic sensing network, and in this architecture, a mechanism to increase the power transmission and reverse transmission in the same direction is proposed. When the sensor transmits the packet, it encounters a situation in which the packet cannot be transmitted normally. The sensor retransmits and waits for the next node to return the packet. If reaching the retransmission upper limit value, the sensor still does not receive the returned Ack, indicating that the next node cannot work normally. At this time, the sensor will calculate the energy consumption between jump and opposite,choose the way that the energy consumption is smaller direction and transmitting the data package.We derive the mathematical formula to calculate the energy consumption and packet delay of the jump and opposite direction transmission. We use Matlab for numerical analysis, and derived mathematical formulas. In the numerical analysis, we change the total number of nodes, the distance, and the length of packets to analyze Energy consumption and packet delay in the underwater acoustic sensor network.
