[0033] Acronyms and key term definitions

[0034] MANET: Mobile Ad Hoc Network, a multi-hop decentralized network composed of a group of wireless mobile nodes. The nodes can freely and dynamically form any temporary network structure. It has strong resistance to destruction and self-organization, and is widely used.

[0035] Betweenness centrality of a node: the proportion of the shortest path containing a certain node v to all the shortest paths in the network.

[0036] Important node: The key node in the encrypted MANET is in a relatively important position in the communication process. Once it fails to work normally, it will affect the information transmission of ordinary nodes.

[0037] Ordinary nodes: Compared with important nodes, they are less important, and failure to work normally will not affect the entire network.

[0038] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the a...

Abstract

The invention relates to a method for recognizing node types in an encrypted MANET (Mobile Ad Hoc Network). The method comprises the following steps: S1, sorting subnetworks in the MANET; S2, distinguishing nodes in the network by using radio positioning according to a sub-network sorting result; S3, performing topology inference on the network on the basis that the network nodes are distinguished; S4, calculating betweenness centralities of the nodes specific to a topology inference result; and S5, judging the node types specific to the betweenness centralities of the nodes. Through adoption of the method for recognizing the node types in the encrypted MANET, automatic recognition of the node types is realized in an information transmission process of the encrypted MANET, and the recognition accuracy is increased.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method for identifying node types in an encrypted MANET. Background technique [0002] At present, the identification of node types is mainly focused on the Internet. By monitoring and analyzing the traffic in the network for a long time, and then realizing the identification of node types through certain methods, it is used to judge the importance of nodes in the network. By determining important nodes Then implement public opinion management. The index used to judge the importance of nodes is mainly the degree of nodes. Among them, the degree is an intuitive consideration of the influence of neighbor nodes on the node. The higher the degree, the more central the node is in the network. The degree of node i is defined as the number of neighbors of the node. [0003] Taking the degree of a node as a measure of the importance of a node, it is believed that the more e...
