Problems solved by technology

[0004] Although the existing technology can realize the direct assessment of the failure node, the vehicle mobility requires that the trust assessment should be carried out quickly. However, the sensing range of each vehicle is limited by buildings or other vehicles. The event needs to be evaluated based on the information received from other nodes, and due to the delay in information transmission and the low reliability of information, the evaluation accuracy of the failed node is low

Abstract

The embodiment of the present application discloses a failed node detection method, device and related equipment, wherein the method includes: obtaining node evaluation factors, the node evaluation factors include cooperation factors, credibility factors, responsibility factors and capability factors; according to the node The evaluation factor generates a node fuzzy value; generates a node trust value according to the node fuzzy value; judges whether the node trust value of the target node is less than a preset threshold, and the target node has an associated relationship with the node evaluation factor; if so, the The target node is a failure node; if not, the target node is not a failure node.

Description

technical field [0001] The present application relates to the field of vehicle-mounted Internet of Things, and in particular to a method, device and related equipment for detecting failure nodes. Background technique [0002] The Internet of Things is another revolutionary breakthrough in information technology after personal computers and networks. After more than ten years of gestation, the Internet of Things has attracted strong attention from all over the world in recent years. The in-vehicle Internet of Things is the concrete embodiment and application of the Internet of Things in the transportation industry. The vehicle-mounted Internet of Things system uses advanced sensing technology, network technology, computing technology, control technology, and intelligent technology to conduct comprehensive perception of roads and traffic, and realize the interaction of large-scale and large-capacity data between multiple systems. Cars control the whole traffic, and control t...
