Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] Research on source node location privacy protection based on multi-channel interference in underwater acoustic sensor network, the steps include:

[0043] Step 1: If figure 1 Shown, node clustering method selection. Based on the Ekman drift model, there are two layers in the network, namely the dynamic layer and the static layer. In the dynamic layer, since the velocity and direction of the ocean current change with the depth, the meanshift algorithm is used for clustering. The meanshift algorithm has a dynamic clustering effect without any preset parameters, and can adaptively adjust the number and size of clusters as the scene changes. The result of meanshift clustering is as follows figure 1 Shown in dark gray clusters. In the static layer, since the ocean current velocity is almost 0, it remains static. Therefore, the k-means a...

Abstract

The invention relates to a multi-channel interference source node position privacy protection method in an underwater acoustic sensor network, which comprises the following steps of: firstly, respectively selecting a node clustering mode and a region division mode according to the characteristics of a static layer and a dynamic layer in combination with an Euckmann drifting model; secondly, in order to cope with monitoring attacks of attackers, combining source-pseudo data hybrid transmission and MAC layer multi-channel interference, covering a source data channel with multi-pseudo data channel interference, and protecting the position privacy of a source node; after multi-channel interference data transmission is utilized, enabling an underwater node to use a principal component analysistechnology to reduce the dimension of a sensing signal, enhancing the AUV movement sensing of the node, then predicting the AUV movement direction by using an equal SNR curve, and adjusting the working state of the node in time; and finally, enabling the AUV in each region to plan a data collection route through an ant colony algorithm, and transmitting data to the mobile base station after data collection. According to the method, the success rate of attack monitoring of an attacker can be hindered, the collection efficiency of underwater data is improved, the default known precondition of the node position is abandoned, and the protection of the source node position privacy in the underwater environment is enhanced.

Description

technical field [0001] The invention relates to a location push-based source node privacy protection method in an underwater acoustic sensor network, and belongs to the technical field of wireless sensor network communication support. Background technique [0002] The location privacy protection of underwater acoustic sensor networks is derived from the location privacy protection of wireless sensors, and is often combined with data transmission and collection schemes. Since underwater acoustic sensor research is in its infancy, we first introduce location privacy protection in wireless sensor networks. The location privacy protection of wireless sensor networks has experienced certain development, which is mainly divided into three aspects of protection: (1) location privacy protection for source nodes; (2) location privacy protection for base stations; (3) at the same time for source nodes and base station for protection. These three aspects have something in common. Fi...
