Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing:

[0035] refer to figure 1 , a node deployment and networking method based on an underwater acoustic sensor network, the underwater acoustic sensor network includes a plurality of common underwater sensor nodes 1 , a plurality of underwater mobile nodes 2 and a plurality of surface buoy nodes 3 . It adopts hierarchical clustering method to cover the target water area, and divides the network into three levels, and each level is divided into several continuous three-dimensional spaces. Underwater ordinary sensor node 1 senses and collects surrounding physical environment data according to the floating control modules evenly distributed in different levels and different depths of the target area, and forms several self-organizing clustering networks with acoustic links. Common underwater sensor nodes 1 belonging to the same three-dimensional space form a cluster, and non-clust...

Abstract

The invention relates to underwater acoustic sensor networks and a node deployment and networking method thereof. A target water area is covered in a hierarchical clustering manner, the networks are divided into three hierarchies, and each hierarchy is divided into multiple continuous 3D spaces; common underwater sensor nodes are uniformly distributed in different depths of the different hierarchies of the target area, sense and collect physical environment data of the surrounding, and form self-organizing clustering networks via the sound wave links; movable underwater nodes can move in the target water area, assess the water quality change of routes, and directly transmit an assessment result to water surface buoy nodes; and the water surface buoy nodes is mixed with communication modules, receive, process, gather and integrate underwater network data via the sound wave communication module, and transmit the network data to a land base station in the multi-hop manner via the radio electromagnetic wave communication module. The underwater acoustic sensor networks and the node deployment and networking method thereof can realize remote monitoring, is wide in monitoring range, high in expansibility and reliability, suitable for underwater applications, and has a good application prospect.

Description

【Technical field】 [0001] The invention relates to a network communication system, in particular to an underwater acoustic sensor network and its node deployment and networking method, and belongs to the technical field of underwater acoustic sensor network communication networking. 【Background technique】 [0002] Underwater Acoustic Sensor Networks (UASNs) is a wireless network formed by self-organization of multifunctional miniature underwater sensor nodes with acoustic communication links. It uses the sensor module assembled by the underwater sensor node to collaboratively monitor, perceive and collect the data of the measured object in the underwater environment in real time, and controls the up and down floating of the node by means of the buoy module and the air pump assembled by it, and is arranged at different depths to form Three-dimensional network, and use its own processor and memory to process and store respectively. At the same time, each underwater sensor node ...
