“…In [15], an approach based on a partially observable Markov decision [16] partially observable Markov decision process (POMDP) process is proposed to maximize SU throughput by jointly tuning spectrum sensing, access, and physical layer modulation coding schemes. Literature [17] proposes a differential game [18] based framework for laboratory optimal congestion control to adjust the rate of SU flows. The framework can balance predictablex contact, non‐cooperation, and rate‐based congestion among sub‐users while utilizing the primary user's free spectrum.…”

In order to solve the network congestion problem caused by burst service flows in heterogeneous cognitive radio networks (Het‐CRN), a two‐stage dual‐threshold random early detection (TD‐RED) control mechanism is proposed here. Meanwhile, a three‐state Markov modulated Poisson process (MMPP‐3) is used to model the burst service to analyze its arrival in depth. Moreover, a performance evaluation system (PES) is proposed to quantify the interference of burst services to different classes of services and their quality of service, which can comprehensively evaluate the performance enhancement of the TD‐RED control mechanism for each service. The system examines performance metrics such as packet loss rate, average delay, average captain etc. PES simulation results show that TD‐RED significantly reduces the packet rejection rate and transmission delay compared to the no congestion control (NCC) and random early detection (RED) methods, thus providing superior quality of service to all services. thereby providing a superior quality of service to cognitive users. Its lower average captain fully proves that TD‐RED can effectively alleviate congestion.

This paper investigates a multi‐pursuer single‐evader nonzero‐sum differential game. Unlike traditional treatments, cooperative tracking is considered to design the optimal pursuit strategy by introducing a novel weighted topology and a scalar coupling gain. First, the distributed control strategy is designed based on the Hamilton–Jacobi–Isaacs (HJI) under the nonzero‐sum differential game. Then the modified LQR‐based cooperative tracking strategy is applied to achieve cooperativity among all the pursuers. The interception condition is also analyzed using a coupling gain based on the Laplacian matrix. Several illustrative examples under different scenarios are presented, and the results show that the pursuers with the proposed strategy can successfully intercept the evader.

This article investigates a multiplayer nonzero‐sum differential game (MNDG) with switching topology and input delay. The Hamilton–Jacobi–Isaacs (HJI) equation is used to derive the optimal control strategies. To solve the issue of switching topology, the control strategies are decoupled with the communication topology. Then, the stability of the system can be achieved regardless of changes in communication topology with the designed control strategies. This does not require a restriction on the dwell time, making the system stability conditions more relaxed. The Lyapunov–Krasovskii functional (LKF) is constructed to prove the stability of the system in the presence of time‐varying input delay. To cope with the real‐world situation, the input delay is considered to be disturbed by a time‐varying perturbation in this article. With these treatments, the system is more in line with real‐world applications. Simulation examples are given to validate the efficiency of the presented methods.
