Abstract

The invention relates to a method and system for calculating the upper and lower bounds of the number of full-coverage underwater sensor network nodes, wherein the method includes: discretizing the area information of the network nodes to be deployed; judging whether ordinary sensor nodes in the area are connected to ordinary sensor nodes; Determine whether each common sensor node in the area is connected to the base station node; calculate the upper and lower bounds of the optimal number of underwater sensor network nodes based on the constraints on the number of fully connected network nodes. The present invention considers the connectivity between ordinary sensor nodes and ordinary sensor nodes, ordinary sensor nodes and base station nodes to form a fully connected network, thereby effectively improving the network connectivity rate of small-scale water areas and ensuring that the information collected underwater can be accurately transmitted to Base station; and from the perspective of minimizing the number of underwater sensor nodes, the optimal number of network node deployment under full coverage can be obtained through the relationship between the upper and lower bounds of the optimal number of nodes, so as to improve the network coverage of small-scale waters and reduce costs.

Description

Technical field[0001]The present invention relates to the field of data processing, and specifically, a full-covered underwater sensor network node number up and down circuit calculation method and system.Background technique[0002]In recent years, with the rise of national development of marine economic boom, people pay particular attention to the monitoring of marine resources, the monitoring of marine environments. However, due to the traditional two-dimensional wireless sensing network (WSN) can only rely on fading acoustic signal transmission information, high node cost, network energy consumption, etc., does not apply to complex and variable underwater environments .[0003]Underwater Wireless Sensor NetWorks, UWSN can be collected and completed by the information of the designated area due to its low energy consumption and the self-organizing capability of the node can be used in the case of communication distance. There are many advantages such as data collection and finishing....
