摘　　要：归纳了一种通用的水下节点光通信模型,引入节点存活率作为海底观测网的可靠性指标,针对水下多分支节点较多导致的可靠性降低和铺设施工难度增加等缺点,将NEPTUNE优化为只包含两个多分支节点的交叉环拓扑。对上述两种网络的可靠性进行了仿真,结果表明,交叉环拓扑与NEPTUNE相比具有相近的可靠性,但多分支节点数量更少,便于海底观测网的供电和铺设。This paper first summarizes a general optical communication model for underwater nodes and takes node survival rate as the reliability index of cabled seabed observatory networks. In view of reduced reliability and increased difficulty in cable installation arising from multiple underwater branching nodes, it optimizes NEPTUNE into a crossed ring topology that contains only two multi-branching nodes. The reliability simulation results of the above two kinds of networks reveal that the crossed ring topology is similar to NEPTUNE in reliablity, but more favorable for power supply and network installation because of less number of branching nodes.
