Problems solved by technology

However, in the specific implementation, the obtained trust value is not specifically quantified, nor is it used in the key algorithm
[0005] The reason why the current solutions are difficult to fundamentally solve the above problems is mainly because the sensor network is limited by the following two factors: energy consumption issues and capacity issues

Embodiment Construction

[0042] The present invention will be further described below through specific embodiments.

[0043] A mobile trusted data collection method based on trust value utility in sensor networks. In the application of wireless sensor data collection, a node trust evaluation algorithm (such as direct trust and indirect trust) is designed according to the relationship between nodes. There is an algorithm to obtain the quantitative trust value of the node. According to the obtained trust value, a credible cluster head node is generated in the subsequent cluster head node election. Finally, according to the Euclidean distance between each cluster head node and the trust value of the relevant next-hop node, the next node with the largest utility value is calculated, so as to generate a trusted path with the largest trust value and utility. The mobile edge nodes visit the trusted cluster head nodes sequentially within a limited moving distance, collect credible sensing data, send it to th...

Abstract

The invention relates to a mobile trusted data collection method based on trust value utility in a sensor network, which comprises the following steps of: designing a node trust evaluation algorithm (such as a direct trust value and an indirect trust value) according to the relationship between nodes in the application of wireless sensor data collection, and obtaining a quantized trust value of anode by an existing algorithm; and according to the obtained trust value, generating a trusted cluster head node in the subsequent cluster head node election; finally, calculating the next cluster head node with the maximum trust utility value according to the Euclidean distance between the cluster head nodes and the trust value of the related next hop cluster head node, thereby generating a trusted path with the maximum trust utility value.

Description

technical field [0001] The invention relates to the field of information security of a large-scale wireless sensor network, in particular to a mobile credible data collection method based on trust value utility in a sensor network. Background technique [0002] In recent years, cloud computing technology has developed rapidly, which can provide users with a variety of cloud computing services, expand the application space of sensor networks, and provide new ideas for solving many limitations of sensor networks. For example, in environmental monitoring applications, a physical sensor node can simultaneously monitor multiple information such as temperature, humidity, and carbon dioxide concentration. The services provided by the cloud platform can be virtualized into multiple sensor nodes, which can be conveniently used by multiple users, which not only reduces the cost, but also improves the utilization rate. Through the cloud platform, users can obtain the data they need wi...
