【摘要】 针对自主航行场景下的船舶通讯网络节点稀疏且移动速度快、高度异构的特性和灵活动态的网络组织需求,提出了一种多组网模式转换的船舶自组织网络架构。该架构针对不同的航行场景提出了全联通的会遇模式和分层成簇的巡航模式二种网络组织方法,满足不同的航行任务和航行场景雪球,并设计了二种模式的切换机制。针对网络管理中出现的各种情况,提出了网络管理的具体方法,对船舶节点的入网与脱离、簇首节点选举和替换、航行管理等设计了具体的措施。分析表明,该体系架构在一定程度上可以满足船舶自主航行的需求,可靠性较高,具备一定的实操性。更多还原

【Abstract】 In view of the sparse, fast moving, highly heterogeneous characteristics and flexible and dynamic network organization requirements of ship communication network nodes in autonomous navigation scenarios, a ship self-organizing network architecture with multi-group network conversion is proposed. The architecture proposes two network organization methods: fully-connected meeting mode and hierarchical clustering cruise mode for different navigation scenarios, to meet different navigation tasks and navigation scene snowballs, and designs a switching mechanism for the two modes. In view of various situations in network management, specific methods of network management are proposed, and specific measures are designed for the entry and detachment of ship nodes, the election and replacement of cluster head nodes, and navigation management. The analysis shows that the system architecture can meet the needs of ship’s autonomous navigation to a certain extent, with high reliability and certain practicality.更多还原
