Research On Network-Nodes Convergence Method Based On Information Pre-Allocation In Aerospace Measurement And Control Network

With the development of times,more and more countries will enter deep space,and at the same time,the variety of satellites for different projects and the diversity of operational tasks will become more and more important.Under this premise,compared with the previous days,the signal interference between the satellite is more and more serious,the mission conflicts will increase and the enemy interference and information intercept will increase.Therefore,according to the multiple interference,task conflict and the increase in the space measurement and control network,this paper studies the flexible transmission of information in the application layer,so as to ensure the communication capacity quality of the network transmission and increase the security of information transmission.In this paper,we study a multi-network nodes convergence method based on information predistribution.The main work completed in the paper is as follows:(1)a multi-node convergence scheme is proposed.In the task of the downlink of the transmission,there are multiple receiving stations and receiving channel,each channel for its own maximum bandwidth and channel parameters,for different tasks,multiple indicators after selected channel,obtain bandwidth information,will transfer information according to bandwidth ratio,to different channels for transmission,finally all the transmission channel’s information will convergence in the control center.While ensuring the channel reception rate,try to save the channel resources and make the information transmission more flexible.This paper also designed the channel selection algorithm.The channel capacity of each channel is calculated,and several channels consuming the smallest resources are selected for transmission if the channel capacity is meet and the task can be completed.(2)Improve the artificial bee colony algorithm for optimization.Under the premise of the channel parameters are input into the artificial bee colony algorithm,the algorithm will calculate the bandwidth of the suitable channel to meet the current task.According to the calculated bandwidth ratio,the information is allocated in advance and handed over to the selected channels for transmission respectively.After arriving at the information station,the information is spliced into the complete information again.(3)Expand the data set.This paper uses the GAN algorithm,the basic square wave and the modulation signal are trained to generate multiple modulated signals and expand the signal set data.
