Special Issue Information

Dear Colleagues,

The Internet of Things (IoT) is revolutionizing daily life, but artificial intelligence (AI) truly unlocks its full potential. Three pivotal emerging technologies—AI, 5G networks, and big data—are enhancing IoT, culminating in the Artificial Intelligence of Things (AIoT). The primary objective of AIoT is to bring intelligence to the edge, enabling devices to recognize data, evaluate their environments, and determine optimal actions. Through AI, IoT devices have evolved into sophisticated machines capable of autonomous analytics and independent decision making, far surpassing their initial roles as mere data transmitters.

Nonetheless, the integration of IoT and AI in the context of smart and autonomous systems introduces critical challenges for the research community. A crucial step in realizing the full potential of AIoT is fostering collaboration among massive distributed devices. Without such collaboration, AIoT systems may encounter issues such as inefficient energy use, security vulnerabilities, and inconsistent performance. Another essential aspect is the seamless integration of AIoT with other cutting-edge technologies. Both academia and industry must prioritize bridging the gap between AIoT with 5G networks, edge computing, blockchain, digital twin, and other emerging technologies to achieve comprehensive convergence.

This Special Issue seeks high-quality contributions from experts in academia and industry in the fields of AIoT, machine learning, 5G networks, and big data. We solicit high-quality original papers on the development of AI models for IoT systems and the presentation of pioneering approaches and applications.

The topics of interest include, but are not limited to, the following:

  • Novel AIoT architectures and frameworks;
  • Integration and application of 5G networks with AIoT;
  • Security and privacy solutions for AIoT against malicious attacks;
  • Intelligent edge/fog/cloud computing;
  • Integration of large language model (LLM)/large vision model (LVM) and AIoT;
  • AIoT-Enabled Semantic Communication;
  • Distributed Collaborative Learning in AioT;
  • Robust distributed AIoT design in smart and autonomous system;
  • Interplay between digital twin and AIoT over networks;
  • Novel methods for AIoT solutions with limited communication/computation resources;
  • AI-driven applications in smart homes, smart cities, and smart industries.

We look forward to receiving your contributions.

With the increasing application of federated learning to medical and image data, the challenges of class distribution imbalances and Non-IID heterogeneity across clients have become critical factors affecting the generalization ability of global models. In the medical domain, the phenomenon of data silos is particularly pronounced, leading to significant differences in data distributions across hospitals, which in turn hinder the performance of global model training. To address these challenges, this paper proposes FedCon, a federated learning method capable of dynamically adjusting aggregation weights, while accurately evaluating client contributions. Specifically, FedCon initializes aggregation weights based on client data volume and class distribution and employs Monte Carlo sampling to effectively simplify the computation of Shapley values. Subsequently, it further optimizes the aggregation weights by comprehensively considering the historical contributions of clients and the similarity between clients and the global model. This approach significantly enhances the ability to generalize and update the stability of the global model. Experimental results demonstrate that, compared to existing methods, FedCon achieved a superior generalization performance on public datasets and significantly accelerated the convergence of the global model.

This paper investigates the secure communication in the reconfigurable intelligent surface (RIS)-aided cell-free massive multiple-input multiple-output (CF-mMIMO) system in the presence of an eavesdropper (Eve). Since the RIS can only reflect the incident signal from its front, we define the RIS coverage and non-coverage area based on whether the incident signals can be reflected. The RIS coverage area is affected by the deployment position and rotation angle, and thus, we take both of these two factors into account and a closed-form approximation for the ergodic secrecy rate of the legitimate user is derived. Based on it, the optimal RIS deployment position and phase shift are obtained through an alternating iteration method, and the optimal RIS angle is achieved through an exhaustive enumeration of angles with a certain interval. Simulations confirm that our optimal RIS deployment can achieve a superior secrecy rate. We find that to guarantee the best secrecy rate, the RIS should be placed near the target user, and its rotation angle should be adjusted to make as many access points (APs) as possible within the RIS coverage area.

The integration of blockchain and federated learning (FL) has emerged as a promising solution to address data privacy and security challenges in Intelligent Unmanned Ports (IUPs). However, existing blockchain federated learning (BFL) frameworks encounter significant limitations, including high latency, inefficient data processing, and limited scalability, particularly in scenarios with sparse and distributed data. This paper introduces a novel multi-chain federated learning (MFL) framework to overcome these challenges. The proposed MFL architecture interconnects multiple BFL chains to facilitate the secure and efficient aggregation of data across distributed devices. The framework enhances privacy and efficiency by transmitting aggregated model updates rather than raw data. A low-frequency consensus mechanism is employed to improve performance, leveraging game theory for representative selection to optimize model aggregation while reducing inter-chain communication overhead. The experimental results demonstrate that the MFL framework significantly outperforms traditional BFL in terms of accuracy, latency, and system efficiency, particularly under the conditions of high data sparsity and network latency. These findings highlight the potential of MFL to provide a scalable and secure solution for decentralized learning in IUP environments, with broader applicability to other distributed systems such as the Industrial Internet of Things (IIoT).

Detecting anomalies in engine and machinery data during ship operations is crucial for maintaining the safety and efficiency of the vessel. We conducted experiments using device data from the maritime industry, consisting of time series records from IoT (Internet of Things) datasets such as cylinder and exhaust gas temperatures, coolant temperatures, and cylinder pressures collected from various sensors on the ship’s equipment. We propose data enrichment and validation techniques by generating synthetic outliers through data degradation and data augmentation with a Transformer backbone, utilizing the maritime operational data. We extract a portion of the input data and replace it with synthetic outliers. The created anomaly data are then used to train the model via a self-supervised learning approach. Synthetic outliers are generated using methods such as the arithmetic mean, geometric mean, median, local scale, global scale, and magnitude warping. With our methodology, we achieved a 17.23% improvement in F1 performance compared to existing state-of-the-art methods across five publicly available datasets and actual maritime operational data collected from the industry.
