Abstract

The invention discloses a multi-AUV cooperative data collection method based on region division in an underwater acoustic sensor network. The multi-AUV cooperative data collection method comprises thefollowing steps: (1) carrying out node state perception and region division of an underwater network; (2) predicting the state of multiple AUVs; (3) planning and updating a data collection path of the AUV; and (4) scheduling type data forwarding. According to the invention, on the basis of network region division; an effective data collection method is executed by utilizing the spatial distribution characteristics and rapid and flexible energy points of multiple AUVs, and the multi-AUV cooperative collection can effectively improve the underwater data collection efficiency, balance the energyconsumption of the network, reduce the data collection delay and prolong the service life of the network while meeting the current service requirements.

Description

technical field

[0001] The invention belongs to the technical field of multi-AUV data collection of an underwater acoustic sensor network, and in particular relates to a multi-AUV cooperative data collection method based on area division in an underwater acoustic sensor network. Background technique

[0002] The nodes in the underwater wireless sensor network are randomly deployed in the monitoring area that the application system is interested in, and the nodes form an underwater wireless sensor network through self-organization. To perform data collection tasks in an underwater environment, at least three modules are required: a common sensor node, a sink node (Sink) and a task management center. Ordinary nodes can use acoustic communication to send the perceived data to the sink through multi-hop, or use the cluster head to collect the data of nodes in the cluster through the clustering mechanism, and then send it to the sink through inter-cluster multi-hop. Sink sends t...
