Automatic construction method of underwater three-dimensional wireless sensor network

Abstract

The invention discloses an automatic construction method of an underwater three-dimensional wireless sensor network. The invention relates to an automatic construction method of an underwater three-dimensional wireless sensor network. Comprising the following steps: determining an optimal deployment position for target three-dimensional water area modeling, sowing movable wireless sensors to the water surface, autonomously driving the movable wireless sensors to the optimal deployment position, and establishing a communication physical link between the movable wireless sensors to form an underwater three-dimensional wireless sensor network. The method has the beneficial effects that the movable wireless sensor can automatically move to the optimal deployment position, compared with the prior art, the wireless sensor does not need to be manually placed at the set node position, the network construction operation process is automatic, and an additional anchoring or buoy method is not needed.

Description

Technical field [0001] The present invention belongs to the technical field of underwater sensor network, specifically relates to an underwater three-dimensional wireless sensor network automatic construction method. Background [0002] Underwater wireless sensor network is an important part of hydrological information collection network, widely used in marine environment monitoring, water body data collection, underwater intrusion detection and other engineering fields. Because the sensor nodes that make up an underwater wireless sensor network are at different water depths, and their depth is negligible relative to the width and breadth of the network, underwater wireless sensor networks are often regarded as underwater three-dimensional wireless sensor networks. [0003] At present, when building underwater three-dimensional wireless sensor networks, the buoy method or anchoring method is usually used. The buoy method connects the underwater wireless sensor with the surface b...

Problems solved by technology

[0004] However, the networking process of the buoy method and the anchoring method not only needs to manually place buoys or anchor wireless sensors, but also needs to pre-calculate the network topology of wireless sensors and the location of each wireless sensor, and after networking, the wireless sensors in the underwater three-dimensional space position basically cannot be changed

Therefore, whether it is the buoy method or the anchor method, the overall efficiency is not high in the process of building an underwater three-dimensional wireless sensor network, and it is difficult to maintain and update the network in the later stage.
