Research on dynamic cooperative technology of manned and unmanned networked information system by Haijun YE, Guofeng WANG, Zhiyong FENG

“…To meet the needs of information security sharing and systematic dynamic cooperation of manned and unmanned formations and to build a dynamic communication network, firstly, a networked high-precision system time synchronization scheme was designed, using integrated network link management strategy and wireless channel on-demand preference algorithm, and the time synchronization accuracy could be up to 100 nanosecond level.Secondly, a data privacy protection and secure sharing solution for airborne networks was built, implementing communication data security of manned and unmanned formation, and analyzing and discussing the performance and security to prove that the proposed solution has a provable high security strength.Meanwhile, a dynamic cooperation model of manned and unmanned formation was designed to discover, authenticate and revoke each node in real time, perform legitimacy identity verification, optimize allocation scheme for multi-objective information acquisition through multi-machine collaborative construction, differentiated data was used to transmit synchronize data, save network resources, improve data transmission efficiency, and meet the demand of systematic cooperative operations.…”

Design of fairness-driven RSMA-SDMA precoding by Yanjing SUN, Fengzhi CHENG, Jiasi ZHOU, Song LI

“…In view of the minimum user rate and system fairness when the transmit power was limited, a user access mode selection transmission strategy by joint rate-splitting multiple access (RSMA) and space division multiple access (SDMA) was proposed.The precoding design problem of maximizing system fairness was modeled.In order to solve the discrete non-convex optimization problem formed, it was decomposed into two non-convex sub-problems, such as the user access mode selection and the inner optimal precoding design.For the precoding design, a quadratic transform of multidimensional and complex FP was used to transform the precoding design into double rotation, and the closed-form expression of the optimal solution for the outer user access mode selection was obtained.Convex optimization was used to solve the inner precoding design problem, and successively optimize the user access mode selection.An algorithm based on fractional optimization was proposed for the problem, and the optimal precoding vector was designed using the quadratic transform of multidimensional and complex FP to maximize the minimum user rate under power constraints.The simulation results prove that compared with RSMA, SDMA and other transmission strategies, the fairness-driven RSMA-SDMA precoding design improves the minimum user rate of the system and guarantees the system fairness.…”

Dynamic task scheduling method for relay satellite networks based on hierarchical reinforcement learning by Runzi LIU, Tianci MA, Weihua WU, Chenhong YAO, Qinghai YANG

“…In recent years, with the increasing number of various emergency tasks, how to control the impact on common tasks while ensuring system revenue has become a huge challenge for the dynamic scheduling of relay satellite networks.Aiming at this problem, with the goal of maximizing the total revenue of emergency tasks and minimizing the damage to common tasks, a dynamic task scheduling method for relay satellite networks based on hierarchical reinforcement learning was proposed.Specifically, in order to take into account the long-term and short-term performance of the system at the same time, a two-layer scheduling framework implemented by upper-level and lower-level DQN was designed.The upper-level DQN was responsible for determining the temporary optimization goal based on long-term performance, and the lower-level DQN determined the scheduling strategy for current task according to the optimization goal.Simulation results show that compared with traditional deep learning methods and the heuristic methods dealing with dynamic scheduling problems, the proposed method can improve the total revenue of urgent tasks while reducing the damage to common tasks.…”
