A mobile auxiliary networking device and networking method based on underwater acoustic sensor network

Abstract

The invention relates to a mobile auxiliary networking device based on an underwater acoustic sensor network, and a networking method thereof. The mobile auxiliary networking device comprises a water quality sensor module, a gyroscope and acceleration sensor module, an obstacle avoiding sensor module, a tail-brushless motor, a rudder and elevator, a micro controller module, a pump control motor, an underwater acoustic communication module, as well as a solar cell and storage battery dual combination power supply module. The multifunctional mobile auxiliary networking device has two moving patterns, wherein the first pattern is that the mobile auxiliary networking device moves according to a preset route and records water quality variation along the route when the network is in a normal condition; and the second pattern is that the mobile auxiliary networking device intervenes according to network feedback information when a network problem occurs, so as to realize dead-zone-free complete coverage and self-configuration maintenance of the network, and when the network returned to normal, the multifunctional mobile auxiliary networking device returns to the original route to advance. The mobile auxiliary networking device and the networking method thereof have the advantages of simple structure, wide application range, high real-time performance and the like, are applicable to many underwater applications, and have good application prospect.

Description

【Technical field】 [0001] The invention relates to a network communication system, in particular to a mobile auxiliary networking device based on an underwater acoustic sensor network and a networking method thereof, and belongs to the technical field of underwater acoustic wave 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 wave communication links.
