In this paper, we propose an orthogonal frequency division multiplexing (OFDM) based underwater acoustic multimedia system. An essential feature of this system is that it offers larger power and schemes providing significant error protection for the transmission sensor data information that requires higher quality of service (QoS). To realize maximum resource utilization, or minimum total transmission power, we also include an adaptive modulation strategy into the system. Thus, in the proposed underwater acoustic multimedia system, high power, low speed modulation, and scheme providing significant error protection schemes are employed for the transmission of sensor data messages that require a stringent bit-error rate (BER). In contrast, low power, high speed modulation, and less capable error protection schemes are provided for messages that can tolerate a high BER. A simulation is carried out to verify the proper functioning of the proposed system in a practical underwater acoustic multimedia scenario.
