Problems solved by technology

[0009] 1. Control packets will be exchanged between the node and the AUV, and the communication will bring a large energy consumption
[0010] 2. The fixed trajectory of AUV causes the energy consumption of nodes near the trajectory to be faster, which will cause hot spot problems and affect the performance of the network
[0011] 3. The AUV cruise path is too long, resulting in a large end-to-end delay in the network

Abstract

The invention discloses a data collection method based on multi-AUV position prediction in an underwater acoustic sensor network. The method comprises the steps that multiple AUVs cruise in the network according to a predefined spiral trajectory to perform data collection, and the trajectory can be adjusted; the positions and the time for each AUV to enter the network are different; the node comprehensively considers the distance between the node and the AUV and the duration required by the AUV to reach the water surface to select the target AUV; and a neighbor node is selected, and the data is sent to the target AUV through multiple hops. According to the invention, a multi-AUV cruise network is supported for data collection, and the energy consumption of nodes is reduced; and the AUV does not need to broadcast a control packet during network cruising, so that the communication overhead is reduced.

Description

Technical field [0001] The invention belongs to the technical field of wireless sensor network data collection, and specifically relates to a data collection method and system based on multi-AUV position prediction in an underwater acoustic sensor network. Background technique [0002] Underwater Acoustic Sensor Networks (UASNs) is an underwater monitoring network system composed of multiple sensor nodes deployed in the monitoring area. These sensor nodes can sense certain data in the environment (temperature, image, Video, etc.), and transmit the sensed data to the surface control center. As a new information network, the underwater acoustic sensor network has gradually become a field of extremely high research value. It plays an important role in underwater data collection, pollution monitoring, marine exploration and disaster prevention. [0003] The function of the underwater acoustic sensor network is to perceive the data in the monitoring area and transmit it through multipl...
