Simulation of Information Physical Risk Evolution of Dense Transmission Channel Based on Multidimensional Information Feature Mapping
Affected by the harsh environment in the field,it is difficult to ensure the security of dense transmission channels,which reduces the reliability of the transmission network.In order to ensure the security of dense transmission channels and timely risk intervention,the simulation research on information physical risk evolution of dense transmission channels based on multidimensional information feature mapping is implemented.An integrated environmental monitoring system is set up in the field to collect multidimensional influencing factors of physical risk of dense transmission channel information,and the principal component analysis method is used to select the main features of multidimensional information from the influencing factors.A multidimensional information feature mapping model is built between the main features and the risk level.It can get the risk value,compare the level classification table,and judge the information physical risk degree of dense transmission channels.The results show that the information physical risk values of dense transmission channels are all below 0 before 6 days,but the overall trend shows an upward trend.This stage is before the risk occurs.After 6 days,the risk values enter the low-risk area.After 14 days,the risk values pass through low risk,lower risk and medium risk respectively,and finally stays in the high-risk area.It provides a new research idea to ensure the security of dense transmission channels.
