Embodiment Construction
[0085] A cluster dormancy wake-up method based on three-dimensional topology control in an underwater sensor network: comprise the following steps: Step 1: utilize three-dimensional underwater sensor network model to complete marine environment sampling work, sensor node adopts three-dimensional Boolean perception model, sensor node n i The perceptual model of the point is a point coordinate (x i ,y i ,z i ) is the center of the sphere, and the perceived radius r s sphere with radius;
[0086] The sensor nodes are laid out layer by layer. First, the nodes are randomly placed on the bottom of the water, and then the sensors are pushed to the water surface by buoys. The length of the rope for the first time is Repeat the above action, the nth rope length is adjusted to in m represents the height of the monitoring area;
[0087] Step 2: analyze the energy consumption of each part of the sensor, and determine the energy consumption model;
[0088] The energy consumption ...
