Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0065] According to one embodiment of the present invention, a kind of underwater acoustic sensor network system is provided, and this underwater acoustic sensor network system is the underwater data acquisition network of node hierarchical deployment, and it includes sink node and common sensor node (hereinafter referred to as sensor node).

[0066] Among them, the sink node is a node with strong processing ability, which can fuse the data sent by ordinary sensor nodes and transmit it to the superior receiving unit (such as surface ships, etc.) in a certain way (such as cable, radio frequency, etc.). It consists of a wired or wireless transmitting module, an underwater acoustic communication module, an information processing and storage module, and an energy supply module.

[0067] The sensor node is a node that can convert the underwater inf...

Abstract

The present invention provides an underwater acoustic sensor network system, including a convergence node and a sensor node, the convergence node is a layer 0 node, and the sensor node whose distance from the convergence node is within the underwater acoustic communication limit distance is a layer 1 node; for each The i-th layer node, except the upper layer node and the same layer node, the sensor node whose distance to the i-th layer node is within the limit distance of underwater acoustic communication is the i+1 layer node; the sensor node is used to upload the node to the upper layer node Collected data, forward the data uploaded by the lower nodes to the upper layer nodes, and send or forward control information to the lower layer; the sink node is used to receive the data uploaded by each sensor node layer by layer, and send control information to the lower layer nodes. The invention also provides a corresponding topology initialization method. The invention satisfies the requirements of the sparse deployment mode; each node has a reliable data upload link; precise synchronization and timing are not required; and it is applicable to irregular network shapes.

Description

technical field [0001] The invention relates to the technical field of sensor networks, in particular, the invention relates to an underwater acoustic sensor network system and a topology initialization method thereof. Background technique [0002] Traditional terrestrial wireless sensor networks are composed of a large number of cheap micro-sensor nodes deployed in the detection area, and form a self-organizing system with a certain topology through wireless communication. It is self-organizing, dynamic, data-centric, and applications are closely related. The nodes in the wireless sensor network can use various types of sensors (such as sound, light, electricity, thermal sensors, etc.). Electromagnetic waves are used as carriers for transmitting data. As far as the topological structure is concerned, the current wireless sensor networks mainly include star network, point-to-point network, self-organizing network and clustering network. It is difficult for the above-menti...
