These servers provide cost-effective solutions that make storage and computing accessible to ordinary users. However, they might face significant vulnerabilities, including data leakage, metadata spoofing, insecure programming interfaces, malicious insiders, and denial of service. To gain public trust in distributed computing, addressing concerns related to privacy and security while ensuring high performance and efficiency is crucial. Multiparty computation, differential privacy, trusted execution environments, and federated learning are the four major approaches developed to address these issues. This survey paper reviews and compares these four approaches based on a structured framework, by highlighting recent top-tier research papers published in prestigious journals and conferences. Particular attention is given to progress in federated learning, which trains a model across multiple devices without sharing the actual data, keeping data private and secure. The survey also highlights federated learning techniques, including secure federated learning, by detecting malicious updates and privacy-preserving federated learning via data encryption, data perturbation, and anonymization, as new paradigms for building responsible computing systems. Finally, the survey discusses future research directions for connecting academic innovations with real-world industrial applications.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"3710-3744"},"PeriodicalIF":6.3,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10963898","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designing a dynamic precoder that can adjust the trade-off between the sensing performance and communication capacity for ISAC systems is typically highly compute-intensive owing to requiring solving non-convex problems. Such complex precoders cannot be efficiently implemented on hardware to operate in highly dynamic wireless environments where channel conditions rapidly vary. Accordingly, we propose an unsupervised DL-based precoder design strategy that does not require a data set of the optimum precoders for training. The proposed DL-based precoder can also adapt the trade-off between the communication sum rate and sensing accuracy depending on the required communication and/or sensing performance. It offers a low-complexity precoder design compared to conventional precoder design approaches that require iterative algorithms and computationally intensive matrix operations. To further reduce the memory usage and computational complexity of the proposed precoding solution, we have also explored weight quantization and pruning techniques. The results have shown that a quantized and pruned deep neural network (DNN) can achieve 96% of the sum rate achieved by the full DNN while its memory and computational requirements are less than 17% of the full DNN.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"3543-3554"},"PeriodicalIF":6.3,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10962172","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research proposes a novel technique for self-organization that integrates Feed Forward Neural Network (FFNN) and Particle Swarm Optimization (PSO) to enhance the network management, optimization and adaptive learning in 6G. The traditional self-organization models in ICNets and 6G depends on rule-based heuristic, reinforcement learning and classical optimization techniques, which often struggle with high computational complexity, slow convergence rates, and suboptimal decision making. In contrast, FFNN+PSO fusion model leverages the predictive learning capability of FFNN and the global optimization strength of PSO to ensure intelligent self-optimization, real-time adaptability, and ultra-low-latency in the dynamically changing 6G environments. The experimental results demonstrate that the proposed method achieves a significantly higher accuracy of 98.25% by outperforming the existing models such as Random Forest (80%), Reinforcement learning (90%), Max Overlapping (88%), and Ant Colony Optimization (92%), Further, the proposed method enhances the energy efficiency, complex network function approximation, and collaborative optimization which make it an ideal choice for scalable and self-organization model in the 6G and ICNets. This study provides a transformative contribution to self-organization in the 6G networks and it offers robust, high-performance alternative to the conventional models as well it ensures massive device connectivity with intelligent network adaptation.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"3816-3833"},"PeriodicalIF":6.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10960282","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work demonstrates a novel approach to advance multi-beam radiation patterns in indoor optical wireless networks by utilizing a cluster-based optical aperture comprising IR radiative elements. Spatially distributed IR clusters permit a non-uniform spherical wave model to focus the radiation in the near-field regime. By executing sub-clusters within main clusters and assigning them to groups for phase delay compensation, we ensure the generation of independent narrow beams focused on each receiver simultaneously. To mitigate the grating lobe formation, we incorporate a dual-carrier framework that introduces an effective wavelength for the system. Based on this theoretical model, we examine multi-beam focusing with a systematic arrangement of clusters on a planar ceiling. It follows a phased array within a phased array structure and incorporates a sub-cluster segmentation algorithm. We suggest optimizing cluster excitation based on receiver positions to enhance power efficiency and safety. This involves selecting the optimal clusters from a uniform array by solving a multiobjective non-convex binary optimization problem, aiming to maximize receiver intensity, minimize intensity variations, and reduce side lobes level. Instead of stochastic algorithms, we adopt a sparse relaxation-based weighted sum method that convexifies the binary space with <inline-formula> <tex-math>$L_{1}$ </tex-math></inline-formula> norm regularization compensating for convexity. The Transformed problem is solved deterministically via Nelder-Mead simplex without gradients. Simulated results confirm a better multi-beam focusing pattern, effectively balancing three objectives. Our findings pave the way for sustainable indoor optical wireless networks in next-generation communication.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"3624-3643"},"PeriodicalIF":6.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10960412","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, in fluid antenna multiple access (FAMA), each user finds the best port in space that maximizes the signal-to-noise-interference over all the ports, allowing many more users to share the same radio channel without demanding involved signal processing. This paper concentrates on the practical version of FAMA, called slow FAMA (s-FAMA), where the fluid antenna of each user updates its best port only if the fading channel changes. Unlike previous works, where the performance metrics are derived in single/double fold integral, we provide a tractable analysis of the system performance of the s-FAMA scheme. Although s-FAMA schemes require complex analysis, we provide simple yet accurate closed-form approximate expressions for calculating the outage probability (OP) and the multiplexing gain metrics, thus facilitating their numerical evaluation in any computer software. Finally, useful insights on determining the number of ports at the FAS to attain a predefined multiplexing gain in the s-FAMA network are also provided.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"3614-3623"},"PeriodicalIF":6.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10960401","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the idea of APs with antenna arrays that are able to move have gained traction among the research community. Many works evaluate the communications performance of Movable Antenna Arrays (MAAs) that can move on the horizontal plane. However, they require a very bulky, complex and expensive movement system. In this work, we propose a simpler and cheaper alternative: the utilization of Rotary Antenna Arrays (RAA)s, i.e., antenna arrays that can rotate. We also analyze the performance of a system in which the array is able to both move and rotate. We focus on narrowband machine-type communications use cases in indoor scenarios, where multiple devices communicate simultaneously with the same AP in the uplink. The movements and/or rotations of the array are computed in order to maximize the mean per-user achievable spectral efficiency, based on estimates of the locations of the active devices and using particle swarm optimization. We adopt a spatially correlated Rician fading channel model, and evaluate the resulting optimized performance of the different setups in terms of mean per-user achievable spectral efficiencies. Our numerical results show that both the optimal rotations and movements of the arrays can provide substantial performance gains when the line-of-sight components of the channel vectors are strong. Moreover, the simpler RAAs can outperform the MAAs when their movement area is constrained.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"2642-2659"},"PeriodicalIF":6.3,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10950397","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, wireless transmissions of model updates from edge nodes to the coordinating server are vulnerable to jamming, alongside the inherent risk of poisoning the learning process. In this paper, we tackle the problem of coordinated jamming and poisoning attacks in wireless FL networks, where malicious edge nodes disrupt transmissions of legitimate local model updates to the cloud server while injecting poisoned model updates to manipulate the global model. To this end, we introduce two complementary mechanisms operating alternately. First, a robust global model aggregation algorithm is developed to address poisoning attacks by weighting edge nodes’ local model updates using a novel contribution index. The calculation of the index is inspired by the Shapley value, but it offers polynomial complexity compared to existing methods. Subsequently, a distributed power control solution for jamming attack mitigation in the uplink of the FL network is introduced based on Bayesian games with incomplete information. Both legitimate and malicious nodes aim to successfully transmit their model parameters, minimizing transmission power and time to the server, while having probabilistic knowledge about the malicious behavior of the other nodes in the game. The proposed unified approach and each individual mechanism are assessed via modeling and simulation, verifying their effectiveness in mitigating both attacks while achieving a good tradeoff between global model accuracy and consumed time and energy compared to state-of-the-art approaches.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"3745-3759"},"PeriodicalIF":6.3,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10955168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143896491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
