This letter investigates a simultaneous lightwave information and power transfer (SLIPT)-enabled hybrid orthogonal frequency division multiple access and non-orthogonal multiple access (OFDMA-NOMA) technology for visible light communication (VLC) systems operating in a high-frequency fading channel. An optimization problem considering information receiving and energy harvesting performance is formulated by jointly adjusting the inter-pair power allocation factor, direct current bias, and power splitting coefficient. A resource allocation scheme based on a modified arithmetic optimization algorithm (m-AOA) is adopted. The results demonstrate that the proposed resource allocation scheme improves energy efficiency (EE) of the SLIPT-enabled hybrid multiple access VLC system by 15%, while the user fairness is also enhanced compared to the conventional fixed power allocation scheme. © 1989-2012 IEEE.

With the introduction of 5G, users and devices can access the industrial network from anywhere in the world. Therefore, traditional perimeter-based security technologies for industrial networks can no longer work well. To solve this problem, a new security model called Zero Trust(ZT) is desired, which believes in "never trust and always verify". Every time the asset in the industrial network is accessed, the subject is authenticated and its trustworthiness is assessed. In this way, the asset in industrial network can be well protected, whether the subject is in the internal network or the external network. However, in order to construct the zero trust model in the 5G Industrial Internet collaboration system, there are still many problems to be solved. In this paper, we first introduce the security issues in the 5G Industrial Internet collaboration system, and illustrate the zero trust architecture. Then, we analyze the gap between existing security techniques and the zero trust architecture. Finally, we discuss several potential security techniques that can be used to implement the zero trust model. The purpose of this paper is to point out the further direction for the realization of the Zero Trust Architecture (ZTA) in the 5G Industrial Internet collaboration system. © 2024 Chongqing University of Posts and Telecommunications

Polarimetric Imaging LiDAR Based on FMCW and Mueller Matrix for Target Classification

引用

Journal of Lightwave technology 2025年第9期43卷 4063-4075页

作者： Zhang, Longkun Sun, Jianfeng Cong, Haisheng Xu, Qian Lu, Zhiyong Chen, Weibiao University of Science and Technology of China Department of Optics and Optical Engineering Hefei230026 China Chinese Academy of Sciences Key Laboratory of Space Laser Communication and Detection Technology Shanghai Institute of Optics and Fine Mechanics Shanghai201800 China Shanghai Key Laboratory of Satellite Network Shanghai200120 China

We present a three-dimensional (3D) polarimetric imaging light detection and ranging (LiDAR) based on frequency modulated continuous wave (FMCW) coherent detection and Mueller matrix polarimetry techniques for target classification. The proposed 3D polarimetric imaging LiDAR can accurately determine which point clouds (or pixels) are on target without ambiguity, which is generally challenging for conventional imaging LiDAR. To reduce artifacts caused by time-sharing polarization imaging, the spatial parallelism and beam synchronization methods are designed to simultaneously obtain multi-polarization point clouds by using Risley-prism multi-beam scanning. After acquiring the point clouds of the polarized reflection intensity, the long-range target recognition and classification can be preliminarily achieved. After calculating the Mueller matrix, the polarization characteristics of the target can be further characterized, thereby achieving more precise target recognition and classification. It is experimentally validated that the architectural materials and structural details with different polarization characteristics can be effectively distinguished and classified by using different polarization parameters, significantly improving the accuracy of target recognition. This study may open new opportunities for 3D perception of urban architecture. © 1983-2012 IEEE.

A two Stage Mixed Integer Programming Model for Distributionally Robust State Based Non-Intrusive Load Monitoring

IEEE Transactions on Consumer Electronics 2025年

作者： Zhang, Chen Chai, Zimo Yang, Linfeng University of Shanghai for Science and Technology School of Mechanical Engineering Shanghai China Guangxi University School of Computer Electronics and Information the Guangxi Key Laboratory of Multimedia Communication and Network Technology Nanning China

This paper presents a non-intrusive load monitoring (NILM) model based on two-stage mixed-integer linear programming theory. Compared with other mixed integer optimization-based models, this paper model introduces fewer integer variables and richer absolute error function of load decomposition, which makes the power state selection of each device more accurate and the power consumption more accurate fitting. First, to tackle the issues related to noisy load data, an innovative load feature extraction model based on Kullback-Leibler distributionally robust optimization principles is introduced. Then the key features (power boundary/fluctuation features) of each device identified through this robust model are integrated into the constraints of the two-stage NILM model. The two-stage complementary framework includes: the determination of device state interval in the first stage;and the accurate fitting of device power consumption within the device state interval in the second stage. Comparative validation against existing optimization-based models on the AMPds, REFIT, and actual laboratory data sets demonstrate that our proposed model significantly enhances power decomposition accuracy and computational efficiency. In addition, the two-stage complementary framework and load feature extraction model can be applied to other optimization-based models of NILM to improve the computational efficiency of each model and the accuracy of load decomposition. © 2025 IEEE.

Row-Diagonal-Parity (RDP) codes and EVENODD codes are classical systematic array codes and most attention in the literature has been on the generalization of RDP codes. In this work, as generalization of not only RDP codes but also EVENODD codes, we present new construction of φ(L)- dimensional (k + r, k) systematic array codes with r ≤ 4, where L is an odd integer and φ(L) represents the Euler's totient function of L. We explicitly characterize sufficient conditions on the selection of L to make the codes maximum distance separable (MDS). Compared with EVENODD codes and RDP codes, the largest k that can be supported by the new codes is nearly doubled, and the asymptotic encoding complexity of the new codes is same, that is, asymptotically approaches r XORs per original data bit with increasing L and k. Moreover, for prime L, r = 2 and k = 2L-3, the new code exactly achieves the optimal encoding complexity. For the case r = 4, the largest k that can be supported by the new codes is larger than the recently proposed so-called Variants of Extended Shortened Independent-Parity (V-ESIP) systematic array code in a number of code dimension selections, and meanwhile, the obtained explicit conditions on L to guarantee the MDS property of the new codes also apply to classical EVENODD codes and RDP codes, but are more general than well known explicit ones in the literature. The decoding process of the new array codes is also discussed. In particular, the r × r block inverse matrix involved in decoding is explicitly characterized, which applies to all MDS array codes generalized from RDP or EVENODD codes in the literature. © 2025 IEEE.

HIAWSC: An Immune Algorithm Based Heuristic Web Service Composition Framework

Chinese Journal of Electronics 2025年第3期23卷 579-585页

作者： Jiuyun Xu Reiff-Marganiec Stephan School of Computer and Communication Engineering China University of Petroleum Qingdao China Network and Switch Technology Key Laboratory Beijing University of Posts and Telecommunication Beijing China Department of Computer Science University of Leicester Leicester UK

The introduction of of web services has led to web service composition being a focus of many researchers. Composing web services using workflows is seen as the most realistic method from an industrial view-point. Amongst other method, the use of natural computing methods has been proposed previously to automate web service composition. The need for a fast response when computing the most suitable sequence of services is addressed in this paper. In particular, we propose a novel heuristic immune algorithm with an efficient encoding and mutation method. The algorithm involves two steps: an immune selection operation, which is maintaining antibody population diversity and the clonal selection. The use of a vaccine during the evolution provides heuristic information that accelerates the convergence. Our experimental results illustrate that the proposed heuristic immune algorithm is very effective in improving the convergence speed. We also provide a schema analysis for this method.

Sensing-communication-Computation Integration for Federated Edge Learning with Controllable Model Dropout

FEderated Edge Learning (FEEL) is an advanced paradigm in edge artificial intelligence, enabling privacy-preserving collaborative model training through periodic communication between edge devices and a central server. FEEL involves three key processes: sensing, computation, and communication for data acquisition, processing, and exchange, respectively. Due to limited system resources, optimizing each process individually may lead to suboptimal learning performance. This challenge has sparked research into Integrated Sensing-Computation-communication (ISCC) design for enhanced FEEL. While previous work has optimized general learning parameters such as batch size and computing frequency, there is a lack of customized designs considering the neural network architecture as an optimizable variable in ISCC for FEEL. To close this gap, we introduce a novel design where each device generates a sub-model through controllable weight dropout, adding flexibility by directly manipulating the learning process and reducing computation and communication overhead. To guide ISCC resource allocation in this new setting, we present a comprehensive convergence analysis, revealing the tight coupling of sensing, computation, and communication across devices and their impact on FEEL convergence. Building on these theoretical insights, we formulate an ISCC problem aiming to maximize the FEEL convergence rate through joint optimization of variables such as batch size, sensing power, dropout rate, and communication power. This non-convex problem is decomposed into two sub-problems via alternating optimization: one controls batch size using a sorting algorithm, while the other focuses on ISCC device parameters, transformable into a convex problem solved by successive convex approximation. Extensive experiments using human motion recognition datasets demonstrate the superiority of the proposed design over baseline schemes. © 2014 IEEE.
