To overcome the energy constraint, the intermittent control transmission strategy is introduced. Meanwhile, to address the challenge of unknown Markovian models in the leader-follower MNNs, a hidden Markov model (HMM) is utilized to infer unknown modes from observable information. Then, an intermittent nonfragile controller based on HMM is designed for the follower MNNs. Furthermore, the exponential iteration method is employed to establish sufficient conditions for ensuring anti-quasisynchronization for leader-follower MNNs, and an optimal boundary of anti-quasisynchronization is obtained. Ultimately, the effectiveness of the proposed HMM-based intermittent controller is demonstrated via a numerical simulation.","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"37 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To prevent data conflicts caused by communication resource limitations, a round-robin (RR) protocol is introduced to regulate the communication transmission order among coupled nodes. To be more general and flexible against Denial-of-Service (DoS) attacks, the concept of average dwelling time ratio (ADTR) is proposed to evaluate DoS attack models. In addition, a DoS-attack-aware ET mechanism is developed. Under this mechanism, a threshold parameter is dynamically adjusted according to the active and dormant time of the DoS attacks. The correlated co-design of anti-attack security control and ET mechanism is realized. Compared with the existing results, the scheme improves the control performance while reducing the controller update frequency. Then, by establishing appropriate Lyapunov function, sufficient criteria for synchronization of discrete-time FCNs are obtained, and a controllable range of the ADTR is calculated. Finally, the effectiveness of the proposed DoS-attack-aware ET control scheme based on RR protocol is verified through two simulations.","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"12 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144645765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fulfill complicated formation tasks, a TVGFT protocol is proposed, where the agents are decomposed into multiple subgroups and each subgroup can successfully track the corresponding leader. Additionally, novel multiple asynchronous dynamic edge-event-triggered mechanisms (DEETMs) are designed to further conserve communication resources and optimize network utilization by enabling the leader to send information intermittently and allowing each follower to transmit information asynchronously when the trigger mechanisms are satisfied. The DEETMs consider both interlayer and intergroup information interactions to improve communication efficiency. Different from the existing results, the proposed DEETMs are used for intergroup information exchange to enhance both the coordination of formation and information transparency. At last, the simulation experiment is offered to validate the designed protocol.","PeriodicalId":13112,"journal":{"name":"IEEE Transactions on Cybernetics","volume":"21 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the event-triggered technique is utilized to design the multileaders formation tracking protocol with resilience to noncooperative nodes.
