A hierarchy network based on multiple AUVS and sonobuoys

摘要

A design for underwater network management is proposed in this paper. The underwater network is a tree-shaped construction and has several sub-networks. Being a hierarchy network, every sub-network has a center node that is the gateway of the network, and the sonobuoy is played as center node. Autonomous Underwater Vehicles (AUVs) are the common nodes, and equipped with sonar and underwater acoustic communication modern. The multiple tasks can be assigned to different sub-network, or accomplished cooperatively. With communication and detection range constraints, AUVs move in the survey area to get maximum range that obeys the rule of Voronoi participation algorithm. When some mobile node moves away from the prevenient center, the sub-network should be reconstructed, and the node would join in other nearer sub-network. The flexible and robust construction can be used to cooperative target detection and environment inspection.
