Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] A method for updating trust models of underwater acoustic sensor networks based on complex network theory, the steps of which include:

[0040] Step 1: If figure 1 As shown, the network model is constructed. The network is divided into upper and lower parts, namely the upper layer network composed of sink nodes that are stationary on the water surface and the lower layer network composed of underwater moving sensing nodes. The sensing nodes in the lower network are anchored on the seabed, so they can move with the water flow within a certain range, responsible for underwater data collection, and transmit the collected data to the water surface through multi-hop transmission; the sink in the upper network The node is responsible for receiving the data collected by the underwater sensing node, preprocessing the data, and then sending th...

Abstract

The invention relates to a method for updating trust models of underwater acoustic sensor networks based on complex network theory. The steps include: firstly, reflecting the influence of the underwater environment on node communication by defining the connection probability between underwater sensing nodes; secondly, complex Network theory, defining key nodes, and improving the ability of the network to respond to different attacks; finally, based on the Q-learning algorithm in reinforcement learning, a trust model update method is designed. The invention solves the problem that the trust model in the existing underwater acoustic sensor network cannot be updated adaptively according to changes in the underwater environment or attacker means, and improves the practical application value of the trust model in the underwater acoustic sensor network.

Description

technical field [0001] The invention relates to a method for updating trust models of underwater acoustic sensor networks based on complex network theory, and belongs to the technical field of underwater acoustic sensor network communication support. Background technique [0002] The underwater acoustic sensor network is established based on acoustic wave communication. It is a wireless self-organizing sensor network applied in the water environment. It usually consists of several sensor nodes, base stations, satellites and other facilities. The sensor nodes include sea surface buoy nodes and are deployed in water. Or sensor nodes anchored at the bottom of the water, and various types of unmanned underwater vehicles. These devices are responsible for real-time monitoring, perception, collection, and transmission of environmental information, and transmit data to each other through acoustic communication in the water, and then transmit the perceived data to the surface base s...
