[0024] specific implementation

[0025] The specific implementation of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a schematic diagram of an underwater wireless sensor network oriented to point coverage requirements. The monitoring water area is usually modeled by a cube, and the maximum distance in the x-axis direction is x m , the maximum distance in the y-axis direction is y m , the maximum distance in the z-axis direction is z m ; The position of the nodes can be adjusted in the depth direction, and the network coverage objects are random and unevenly distributed target points in the monitoring waters. The present invention will follow figure 2 The described process adjusts the position and status of nodes to realize comprehensive optimization of indicators such as network coverage, connectivity, energy consumption and balance, and life cycle.

Abstract

The invention relates to a novel underwater wireless sensor network point coverage control method. In the method, node depth adjustment is taken as a feasible mobile mode. The method comprises the following steps that: firstly, nodes determine depths of the nodes in reference to a distance between a Sink node and a water surface vertex and the depth of a monitoring water area; secondly, the nodes determine perception radiuses of the nodes according to a distance between the Sink node and a water bottom vertex in reference to a minimum perception radius and a maximum perception radius; thirdly, communication radiuses of the nodes are increased greatly till neighbor nodes with smaller depths are inquired, and a node with a smallest coverage target quantity is selected from a set of the nodes to take the selected node as a cluster head; and lastly, a cluster head node makes inner-cluster nodes hibernate and wake up. Compared with an existing relevant method, the method disclosed by the invention is more feasible. Moreover, indexes such as network coverage, a communication rate, energy consumption and balance, and a network life cycle can be optimized comprehensively.

Description

technical field [0001] The invention relates to a new point coverage control method of an underwater wireless sensor network, which belongs to the technical field of coverage control of an underwater wireless sensor network. Background technique [0002] Underwater Wireless Sensor Networks (UWSN) is a monitoring network formed by some underwater sensor nodes with information collection, storage, processing, and transmission functions in a self-organizing manner, which can complete environmental monitoring and disaster prediction for target waters. , resource detection, military monitoring and other tasks, with a three-dimensional distributed network structure, a wide range of network deployment and sparse node density, nodes use sound waves as communication media, nodes are easily affected by the water environment and move, node energy is limited and difficult to replenish, etc. features. The coverage control problem of the underwater wireless sensor network refers to the r...
