Problems solved by technology

[0005] At present, most incentive mechanisms at home and abroad, such as the CONFIDANT model, do not have a node redemption mechanism, and the redemption mechanism is extremely important for isolated nodes, because perhaps the malicious behavior of this node is due to other non-malicious factors (such as battery battery exhaustion, link failure, etc.)
In addition, many trust models, such as the eigenRep model, do not solve the problems of false recommendation and iterative convergence. At the same time, the model uses the ratio of the number of successful interactions between nodes to the total number of interactions as an individual trust estimate. We believe that the definition is reasonable Debatable, because nodes can fail to interact due to other factors

[0097] Conversion rule of trust degree based on topological transformation

[0098] Suppose in image 3 Calculate N in the network i To N j The trust of N n And N m Two routes. According to the trust conversion method of definition 5, the node N x Copy into two, so that the original topology is converted to a parallel topology, such as Figure 4 Shown. Last N i To N j The total recommendation trust can be based on figure 1 with figure 2 Method of calculation.

[0099] Calculation method of recommendation trust degree based on topological transformation

[0100] Here we are Figure 5 Take an example to illustrate this calculation method. Assuming R 1，3 H , After deleting path "13", the parallel topology is as Image 6 Shown.

[0101] From Image 6 Known in N total Is 3, so set cons to 10. According to equation (8), It should be [1 / 3×10] / 10=0.4. Can be seen here The error is large. In theory, the more nodes there are (the larger the network scale), The higher the accuracy. I...

Abstract

The invention discloses a trust model-based cooperative communication method in a mobile self-organized network. In the method, cooperation of nodes is excited under wireless Ad Hoc network environment by establishing a global trust level and safe recommendation trust level-based trust model and utilizing a trust-fading punishment mechanism and a node salvation mechanism. In the mobile self-organized network, the node determines whether the monitored node participates in the cooperation by utilizing direct monitoring and comprehensive evaluation of monitoring information of other nodes, and a reconstruction mechanism is set for a malicious node, so that the node is newly added into the network and establishes connection with the other nodes; and based on the false recommendation, iterative convergence and punishment and salvation problem of a majority of trust models, the global trust level and safe recommendation trust level-based trust model is established, and a topological transformation-based recommendation trust computation method is brought forward; and in the trust varying process described by the trust model, the cooperation of the nodes is excited under the mobile self-organized network environment by using the punishment mechanism of an updating stage and the salvation mechanism of a reestablishment stage.

Description

Technical field [0001] The invention is a node cooperative communication method based on a trust model of global trust degree and safety recommendation trust degree, and belongs to the cooperative communication technical field of mobile ad hoc networks. Background technique [0002] Collaboration has become a discipline in the fields of social sciences, biological sciences, and mathematics. The most fundamental finding in collaboration is that even egoists will support collaboration when the situation requires it. In the field of information systems, some prominent examples of collaboration have emerged. For example, with the success of open source software, thousands of people have collaborated to create systems such as Linux. In addition, the eBay website based on the feedback system allows strangers to trust each other by verifying the reputation value accumulated by mutual cooperation. [0003] Today, wireless networks now also provide another area for research collaboration...
