在对美军水下网络发展进行研究的基础上,对水下网络的组成、特点、应用等进行简要介绍。水下网络由传感器节点、浮标网关节点、遥控声纳中继节点等组成,尽管由于水声信道的特殊性,使水下网络存在信道带宽窄、数据传输速率低、收发数据率的非对称性、网络配置的机动性和稀疏性、成本高等问题,但它将逐渐被应用于军事海洋环境遥感、战场环境分析、远程水下控制、水下探测、反潜战等领域。
On the basis of research on the development of underwater acoustic network of US army, this paper introduces architecture, characteristic and application of underwater acoustic network. Underwater acoustic network is composed of sensor nodes, buoy gateway nodes, remote control sonar relay node, etc. Due to the particularity of underwater acoustic channel, underwater network has problems of narrow channel bandwidth, low data transmission rate, non-symmetry of re- ceiving-and-sending data rate, maneuverability and sparseness of network configuration and high cost, but it will be gradually used in such domains as military ocean environment remote sensing, battlefield environment analysis, long-range underwater control, underwater detection and so on.
