Barrier construction method for dynamic underwater environment

Abstract

The invention discloses a barrier construction method for a dynamic underwater environment. The method comprises the following steps: 1, an aggregation node control center is established according toan underwater sensor node deploying and controlling water area; 2, the sink node control center calculates the sink depth of each underwater sensor node according to the two-dimensional coordinates ofthe underwater sensor nodes; 3, the sink node control center executes the sinking depth of the underwater sensor nodes and performs information interaction with the underwater sensor nodes in the adjacent water area to establish a neighbor node list of each underwater sensor in the deploy and control water area; 4, whether the underwater sensor node with the maximum weight in the neighbor node list of the underwater sensor is a redundant node or not is judged by using the voronoi graph, and if the condition is met, deleting the node from the neighbor node list of the underwater sensor; according to the method, the coverage rate of the underwater wireless sensor network in the dynamic water area is improved, and energy consumption in the anchor node deployment process is reduced and balanced.

Description

technical field [0001] The invention mainly relates to an underwater wireless sensor network, in particular to a barrier construction method for a dynamic underwater environment. Background technique [0002] Underwater wireless sensor networks are widely used, such as marine information collection, environmental monitoring, deep sea detection, disaster prediction, auxiliary navigation, distributed tactical monitoring, etc. Monitoring target intrusions in key protected sea areas, such as submarines or fish schools, can enable people to obtain more marine information, improve the ability to monitor and predict the marine environment, and help people deal with marine emergencies. In order to reduce the deployment cost and change the traditional cube-filled full-coverage idea, a new detection deployment architecture is used, and sensors with intrusion detection capabilities are used to build an underwater sensor barrier (UWSB) near the underwater channel where the target may pa...

Problems solved by technology

If in the process of moving the node, the distance of the node on the X, Y, and Z axes is changed at the same time, due to the influence of the water flow, the upper boundary may not be covered, so the network coverage of the monitoring area caused by the water flow in the dynamic water area low problem
