However, these indicators are only theoretical indicators, and ignore the comprehensive influence of node structure on information dissemination capabilities. This evaluation will have a large error
At the same time, there are many uncertainties in the dissemination of information on the Internet. At present, there is no index to evaluate the ability of network information dissemination after a large amount of information dissemination on the Internet.

Embodiment Construction
[0054] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0055] In the present invention, by running the information dissemination model multiple times on the network, the corresponding infection rate and success rate are obtained, and the infection rate obtained by the experiment is multiplied by the success rate to obtain the network's information dissemination ability measurement value η, to measure The strength of information dissemination on the Internet.
[0056] The present invention comprises the following steps:
[0057] Step 1: Count the node sequence node_array of the network under test according to the node degree from small to large, and conduct 100 experiments on the same nodes in the sequence. At the beginning of the experiment, initialize the attributes of the nodes. The initialization attributes include node initial The energy is 0, the temporary energy of the node is 0, the received energy time series is...

The invention discloses a method for measuring network information dissemination capability based on node energy model. The method uses the information dissemination model based on node energy to simulate on the network, and distinguishes the success rate and infection rate of nodes by screening nodes with different degrees. After that, the overall success rate and infection rate of the network are corrected by weighting coefficients. The model has good stability, and the experimental results on networks of the same nature and different scales are similar. Therefore, small-scale networks of the same nature can be used to evaluate large-scale networks. In addition, when measuring the ability of network information dissemination, this method also takes into account the influence of success rate on information dissemination ability, and incorporates success rate and infection rate into the evaluation index at the same time. At the same time, this method can also unify the success rate and infection rate under different parameters τ. This method can completely and effectively measure the information dissemination ability of the network.
Description
technical field [0001] The invention relates to the technical field of network information, and relates to a method for measuring network information dissemination capability based on a node energy information dissemination model. Background technique [0002] Measuring the ability of network information dissemination has a wide range of applications in public opinion research, information promotion, and computer virus prevention and control. Since people began to study complex networks, many indicators have been proposed to characterize network characteristics, such as network diameter, triangle number, Node intermediary coefficient, etc. These indicators can show the ability of the network to disseminate information from different aspects. However, these indicators are only theoretical indicators, and ignore the comprehensive influence of node structure on information dissemination capabilities, and this evaluation will have large errors. At the same time, there are many ...
