Embodiment Construction

[0062] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0063] This embodiment provides a UUV cluster ad hoc network method based on underwater acoustic communication, the flow chart of which is as follows figure 1 As shown, it specifically includes the following steps.

[0064] S100: Network establishment: multiple UUV nodes select the master node through a competition mechanism, and other UUV nodes are automatically configured as slave nodes to establish a UUV cluster ad hoc network. In the UUV cluster ad hoc network, the autonomous network status of each UUV node Convert from distributed cluster mode to centralized cluster mode.

[0065] S200: Network merging: when the master nodes of two or more ad hoc networks detect the underwater acoustic network merging signals of other ad hoc network master nodes, they share the information between the master nodes through underwater acoustic...

Abstract

The invention discloses a UUV cluster ad hoc network method and system based on underwater acoustic communication. The method comprises the following steps: network building: a master node is selectedamong a plurality of UUV nodes through a competition mechanism, other UUV nodes are automatically configured as slave nodes, and a UUV cluster ad hoc network is built; network combination: two or more ad hoc networks are combined; network decomposition: a to-be-decomposed network master node transmits an underwater acoustic network decomposition signal, network quitting is executed according to the underwater acoustic network decomposition signal, and the quitted node reestablishes an ad hoc network according to a networking establishment mechanism; and network reconstruction: when the masternode of the UUV cluster ad hoc network is damaged or lost, the competition mechanism reselects a master node, other UUV nodes are automatically configured as slave nodes, and a UUV cluster ad hoc network is reconstructed. A centralized UUV clustering mode and a distributed UUV clustering mode are combined, the method and the system have the characteristics of autonomous state conversion, data exchange, resource sharing and the like, and a node joining / exiting mechanism and a network combining / decomposing mechanism are supported within an acoustic action distance range.

Description

technical field [0001] The present application relates to the technical field of UUV swarm ad hoc network, in particular to a UUV swarm ad hoc network method and system based on underwater acoustic communication. Background technique [0002] UUV (Unmanned Underwater Vehicle) plays an important role in the current ocean exploration, ocean development, military operations and other fields. It can not only complete specific underwater tasks in complex marine environments, but also complete a series of actions such as autonomous navigation, positioning, and obstacle avoidance without human participation. Therefore, the research on UUV not only has important scientific significance, but also has a strong urgent demand in the military field. [0003] As the complexity of underwater operations continues to increase, the previous underwater operations based on single UUVs are difficult to meet the needs of working time, scope, capacity, and efficiency. In recent years, a large num...
