Embodiment Construction

[0014] The influence of marine mammals needs to be considered in the underwater acoustic network. In order to avoid the mutual interference between the data transmission of the gateway and the activities of marine mammals, it is necessary to define the bio-gateway interference area. The determination of the biological-gateway interference area needs to be divided into two parts: the determination of the marine mammal gathering area and the determination of the underwater acoustic interference area. Concrete implementation steps of the present invention are:

[0015] Step 1: Through the long-term observation of marine mammals in the water area to be measured, the statistical observation data and the calculation of the aggregation distribution CA index determine that the Chinese white dolphin is an aggregation distribution type, that is, its existence probability is unevenly distributed in different places in the same area. Therefore, the position observation of marine mammals i...

Abstract

The invention relates to a biofriendly gateway deployment method in an underwater sound sensor network. The method comprises the steps of making statistics on observing data via long-term observation of marine mammals in a water area to be observed, determining a aggregated distribution class by computing an aggregated distribution CA index, and dividing the monitored water area according to different appearance probabilities of the marine mammals; delimiting an MMIR, specifically including that a interference distance is defined to be that when a distance between an interference source and a receiving end is less than the interference distance, an interference signal disables normal communication of a receiving node, and thus a receiving error or receiving interruption is caused; building an underwater sound communication channel module, computing a communication radius and an interference radius of the marine mammals and the communication radius and the interference radius of a water surface gateway, thus acquiring the interference distance of the marine mammals and the water surface gateway; and defining an area by taking the determined marine mammal gather position as a circle center and taking dinf as a radius as a living matter-gateway interference area, wherein no water surface gateway is arranged in the area.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic communication, in particular to a bio-friendly gateway deployment method in an underwater acoustic sensor network. Background technique [0002] With the development of the ocean, Underwater Acoustic Sensor Networks (UASNs) are increasingly being used in commercial, environmental protection and military fields, such as: marine data collection, environmental pollution detection, coastline development, disaster prevention and control, auxiliary navigation and military reconnaissance. However, the complex underwater acoustic communication environment leads to the characteristics of limited bandwidth, high delay, high bit error rate and dynamic changes of nodes in underwater acoustic channels. These characteristics make UASNs face many problems in gateway deployment, channel access, node location, and routing selection. And for underwater acoustic channels, marine organisms, UASNs nodes,...
