However, deploying these systems in real-world healthcare scenarios presents technical challenges, among which load balancing is a key concern. Load balancing aims to distribute workloads evenly across multiple nodes in a network to optimize processing and communication efficiency. This article proposes an adaptive load-balancing method that combines the strengths of static and software-defined networking (SDN)-based load balancing algorithms for edge/fog-based healthcare systems. A new algorithm called load balancing of optimal edge-server placement (LB-OESP) is proposed to balance the workload statically in the systems, followed by the presentation of an SDN-based greedy heuristic (SDN-GH) algorithm to manage the data flow dynamically within the network. The LB-OESP algorithm effectively balances workloads while minimizing the number of edge servers required, thereby improving system performance and saving costs. The SDN-GH algorithm leverages the benefits of SDN to dynamically balance the load and provide a more efficient system. Simulation results demonstrate that the proposed method provides an adaptive load-balancing solution that takes into consideration changing network conditions and ensures improved system performance and reliability. Furthermore, the proposed method offers a 12% reduction in system latency and up to 28% lower deployment costs compared to the previous studies. The proposed method is a promising solution for edge/fog-based healthcare systems, providing an efficient and cost-effective approach to managing workloads.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"18 2","pages":"1139-1150"},"PeriodicalIF":4.0,"publicationDate":"2024-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10543196","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The continuously developing artificial intelligence techniques can be combined with TSN to better adapt the dynamically changing environments. Therefore, we utilize deep reinforcement learning (DRL) algorithms to dynamically configure the network to improve its adaptability. Meanwhile, we propose the queuing transmission method in TAS by incorporating transmission windows for different types of traffic, to make resource allocation simpler and more efficient. However, DRL algorithms usually take a lot of time to train, which is contrary to the delay sensitivity of TAS. Hence, we propose an improved DRL algorithm, called preDQN, where the network prediction is used to help the agent explore the environment more efficiently. Experimental validation is carried out in a simulation environment, and the experimental results show that the scheme can significantly improve the resource utilization, reduce the end-to-end delay and packet loss rate.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"18 2","pages":"997-1008"},"PeriodicalIF":4.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The utilization of this technique is widespread in electronic devices with limited power or resource capabilities due to its high efficiency and low complexity. While clipping effectively diminishes nonlinear distortion stemming from power amplifiers (PAs), it introduces additional distortion known as clipping distortion. The optimization of system performance, considering both clipping distortions and the nonlinearity of PAs, remains an unresolved challenge due to the intricate modeling of PAs. In this article, we undertake an analysis of PA nonlinearity utilizing the Bessel–Fourier PA model and simplify its power expression through intermodulation product analysis. We mathematically derive expressions for the receiver signal-to-noise ratio and system symbol error rate (SER) for nonlinear clipped OFDM systems. Using these derivations, we explore the optimal system configuration required to achieve the lower bound of SER in practical OFDM systems, taking into account both PA nonlinearity and clipping distortion.

The multiagent systems are modeled with two-time-scale structures and the parameter changes are assumed to follow semi-Markov jump processes. For multiagent systems with two-time-scale structures, singular perturbed approaches are introduced to separate the coupled slow and fast dynamics of each agent. Then, double-rate sampling mechanisms are adopted for slow and fast dynamics with different evolution rates, and a novel asynchronous event-triggered scheme (AETS) with two independent triggering conditions is proposed. The asynchronous event-triggered scheme based on double-rate sampled-data reduces the transmission of unnecessary data and saves limited bandwidth resources by triggering independently on two time-scales. In addition, a consensus strategy is proposed to assure the multiagent system of achieving consensus with a specified passive performance level. Finally, the simulation example verifies that the asynchronous event-triggered scheme saves about 50% of network resources than the synchronous scheme under the premise of the same control effect.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"18 2","pages":"1277-1287"},"PeriodicalIF":4.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, decentralized management along considering operational concerns of the system will be a key factor in running the future multiagent systems. Therefore, this article proposes a decentralized framework based on the alternating direction method of multipliers for managing the peer-to-peer (P2P) energy trading in a multiagent distribution system while considering the technical constraints and reliability of the network. This strategy facilitates considering the effects of the network reliability while running the agents’ optimization in a decentralized manner. Respectively, each agent would tend to exchange energy with more reliable agents, which would result in the resilient operation of the network. Moreover, the uncertainty of renewable energy sources is addressed using distributionally robust optimization. Additionally, with the aim of increasing the security of the P2P energy market against communication errors and agents’ misbehavior, an algorithm is developed to identify the existence of a problem in the market convergence as well as how it could be mitigated. Finally, this scheme is investigated on 37 and 69 bus test systems to study its capability in running sustainable energy systems.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"18 2","pages":"905-916"},"PeriodicalIF":4.0,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10478176","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140198348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studied mixed-order MASs include heterogeneous agents which have nonidentical orders of dynamics and different quantities and types of states to be synchronized. To relieve the communication load and decrease the tear and wear due to the frequent regulation of actuators, a distributed cooperative tracking control strategy utilizing the event-triggered mechanism is proposed to realize the final synchronization for all nonlinear mixed-order followers. In addition, the distributed disturbance observer is developed for the heterogeneous followers to lower the impact of unknown dynamics and external disturbances. And, the actuator saturation problem is considered to ensure the wider applicability of the presented control strategy in actual applications. The stability of the controlled mixed-order MASs is proved by Lyapunov theory for ensuring the synchronization of all states under the proposed event-triggered observation-based cooperative control strategy.

In this article, a NS resource allocation optimization algorithm based on multiactor-attention-critic (MAAC) joint with bidding is proposed to guarantee the service satisfaction rate (SSR) while increasing the profit of mobile virtual network operator (MVNO) in heterogeneous integrated networks. First, a pricing and bidding strategies are designed for users with different service requirements and service indexes, and the resource allocation is modeled to maximize the sum of utility of all MVNO subjected to MVNO's pricing and bandwidth constraints accordingly. Second, the optimization problem is analyzed based on the augment Lagrange method, relaxed and has been proved as a convex optimization, and then, the alternating direction multiplier method is adopted to obtain the theoretical upper bound with 32.047 of the network utility. Meanwhile, the gradient descent method with different learning rates is used to accelerate the convergence rate. Third, the MAAC-based algorithm is proposed and the resource allocation procedures are transformed into a partially observable Markov decision process, in which the interactions with multiagent environment are performed accurately. Finally, the simulation results indicate that the network utility of the proposed algorithm can be improved by 25.074% while ensuring the users' SSR. Compared with multiagent deep determination strategy gradient and dueling deep Q network, the network utility by the proposed algorithm can be improved by 6.265% and 39.791%, respectively, up to 27.664, which can be closest to the theoretical upper bound at the greatest extent.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"18 2","pages":"1186-1197"},"PeriodicalIF":4.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141147295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
