    摘要:

    為解決無(wú)人機通信網(wǎng)絡(luò )中數據調度行為中斷概率過(guò)大的問(wèn)題,實(shí)現對通信資源的合理分配,針對基于改進(jìn)機器學(xué)習的無(wú)人機中繼通信數據調度控制方法展開(kāi)研究。設計基本網(wǎng)絡(luò )架構,聯(lián)合BMRC協(xié)議,設置URLLC數據鏈路單元,聯(lián)合相關(guān)通信數據樣本,求解通信中斷概率的具體數值,實(shí)現對無(wú)人機中繼通信網(wǎng)絡(luò )資源的聯(lián)合優(yōu)化處理。分別計算時(shí)隙分配參量與帶寬分配參量,并以此為基礎,確定無(wú)人機中繼位置,實(shí)現對中繼通信資源的調度。按照機器學(xué)習算法標準,定義PCA改進(jìn)特征,從而完善改進(jìn)機器學(xué)習算法,再聯(lián)合最優(yōu)控制器閉環(huán),實(shí)現對通信數據調度行為的控制,完成基于改進(jìn)機器學(xué)習的無(wú)人機中繼通信數據調度控制方法的設計。實(shí)驗結果表明,改進(jìn)機器學(xué)習算法作用下,隨著(zhù)中繼數據累積量的增大,無(wú)人機通信網(wǎng)絡(luò )中數據調度行為中斷概率的最大值只能達到7.3%,有效降低了中斷概率,符合合理分配通信資源的實(shí)際應用需求。

    Abstract:

    In order to solve the problem of excessive interruption probability of data scheduling behavior in unmanned aerial vehicle communication networks and achieve reasonable allocation of communication resources, research was conducted on data scheduling control methods for unmanned aerial vehicle relay communication based on improved machine learning. Design a basic network architecture, combine the BMRC protocol, set up URLLC data link units, combine relevant communication data samples, and solve specific values of communication interruption probability to achieve joint optimization processing of UAV relay communication network resources. Calculate the slot allocation parameters and bandwidth allocation parameters respectively, and based on this, determine the relay location of the UAV to achieve scheduling of relay communication resources. According to the machine learning algorithm standards, define PCA improvement features to improve the machine learning algorithm, and then combine the optimal controller closed-loop to achieve control of communication data scheduling behavior. Complete the design of a drone relay communication data scheduling control method based on improved machine learning. The experimental results show that under the influence of improved machine learning algorithms, as the accumulation of relay data increases, the maximum probability of interruption in data scheduling behavior in unmanned aerial vehicle communication networks can only reach 7.3%, effectively reducing the probability of interruption and meeting the practical application requirements of reasonable allocation of communication resources.
