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 ...

Abstract

The invention relates to a three-dimensional topology control based cluster sleep wakeup method in an underwater sensor network, which comprises the contents below: three-dimensional layout of sensornodes is implemented by utilizing a three-dimensional underwater sensor network model, wherein the sensor nodes adopt three-dimensional boolean sensing models; an energy consumption model is established by analyzing an energy consumption condition of each part of each sensor, and a calculation formula of underwater transmission energy consumption is reconsidered; and a topology model of a three-dimensional dense network is applied. A fragmentation unit and a cluster size are determined on the basis of the models above and related definitions of a cluster sleep scheduling algorithm so as to achieve high coverage, high connectivity and low energy consumption of the network and determine a node level and a sensing radius; and in the premise of considering network quality, proper sleep time and information table are set.
