声电协同海洋信息传输网络

Acoustic-radio cooperative marine information network

海洋信息的传输需要穿越水—空气界面,在信息传输网络架构上需要水声网络和无线电网络的高效融合。然而,水声链路性能远远落后于水上无线电链路,成为制约海洋信息传输网络性能的瓶颈。提出声电协同海洋信息传输网络的新思路,通过声、电链路的协同协作,提高网络的性能。通过3个应用场景展示声电协同的优势后,进一步讨论了声电协同海洋信息传输网络的架构与协议以及面临的技术挑战。声电协同不仅是实现空、海一体化网络融合的有效方法,也是实现海洋网络通信、计算和存储融合的重要方法。

The transmissions of ocean information have to cross the water-air interface. In this case, the information transmission network architecture requires the efficient integration of the underwater acoustic network and the radio network. However, the performance of the underwater acoustic link lags far behind the radio link, and becomes a bottleneck that restricts the performance of marine information networks. An acoustic-radio cooperative marine information network was proposed, which exploited the cooperation of acoustic and radio links to improve network performance. After demonstrating the advantages of acoustic-radio cooperation through three application scenarios, the network architecture and protocols, as well as the challenges for the acoustic-radio cooperative maritime information network were discussed. Acoustic-radio cooperation was not only an effective method for realizing the integration of air-water networks, but also an important method for realizing the integration of network communications, computing, and storage in marine information networks.
