The growing demand for advanced beyond 5G connectivity solutions explores the deployment of end-to-end 5G Non- Terrestrial Networks (NTNs) in cloud-native environments. With the increasing reliance on mobile communications, leveraging next-generation radio access network (NG-RAN) architectures with functional splits has become essential. In the 5G NTN network, some split NG-RAN components can be moved to the satellite node to improve connectivity and resilience. This paper investigates advanced beyond 5G connectivity by deploying end-to-end 5G Non-Terrestrial Networks (NTNs) in cloud-native environments, focusing on Low Earth Orbit (LEO) satellites operating in regenerative mode. Specifically, it explores the implementation of F1 and E1 interface splits within such networks. The first architecture extends the F1 interface over the satellite radio interface (F1 over SRI), linking terrestrial central units (gNB-CU) with satellite-based distributed units (gNB-DU). The second architecture incorporates both F1 and E1 splits, facilitating connections between terrestrial control plane units (gNB-CUCP) and user plane units (gNB-CUUP) on the satellite via the E1 interface over SRI (F1-E1 over SRI). The study's primary goal is to predict the resource utilization-specifically CPU, memory, and bandwidth-of gNB-DU and gNB-CUUP functioning as satellite payloads. Employing Long-Short-Term Memory (LSTM) neural networks, this research aims to enhance network resilience by enabling proactive monitoring and resource allocation decisions, addressing the significant computational and bandwidth demands of payloading gNB-CUUP compared to gNB-DU. © 2024 IEEE.

Data hiding with thumbnail-preserving encryption for cloud medical images

To serve a convenient healthcare network, storing medical images and diagnosis records in the cloud is a straightforward solution. Encrypting the medical images before uploading them to the cloud is a trivial strategy to prevent data breaches. However, the availability of images is also reduced. Since all images look noisy, one cannot obtain the intended image by a quick viewing of the file folder. In this paper, we propose a total solution to these considerations. A reversible data hiding scheme based on thumbnail-preserving image encryption is presented. By leveraging a multi-scale Haar wavelet transform and extended run-length coding, we can produce thumbnail-preserving encrypted medical images that provide a sufficient vacating room for embedding electronic patient records. The experimental results demonstrate that our scheme effectively balances the confidentiality and availability of encrypted medical images. It provides over 1 bit per pixel of capacity for embedding electronic patient records, making it suitable for cloud-based medical data management. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

In AI pandemic applications, the online automatic AI recording apparatus for official councils such as court trials, business conferences and commercial meetings will become imperative because it could let the opinion identification and consensus of participants be synchronically available to implicitly diminish social costs such as follow-up disputes and controversies. Hence, in this study, an automatic on-line multi-dialogue recording system is completely constructed, where the unbounded interleaved-state recurrent neural networks (UIS-RNN) with proposed crux improvements is exploited to achieve confident speaker-diarization. For keeping the systematic robustness, a denoising spectral-LSTM, which is precisely modified from the dual-signal transformation LSTM (DTLN), can strengthen its subsequent crux-improved UIS-RNN and automatic speech recognition (ASR). Finally, the MacBERT model is set to rectify the possible wrong words in conversed sentences according to the learned rational context. For making our system being a practical software apparatus in the use of unmarked multi-person councils, we have also completed the convenient interfaces for the operations of ASR and speaker-diarization, which can exhibit on-line denoising efficacy and speaker-diarization results as well as offer real-time hand-crafted rectifications to common users. In extensive experiments, the proposed recording system can promise high accuracy rates of online speaker diarization and speech-separated ASR. Our proposed system had been examined by the cooperated law court staffs, who offered the noise-embedded speeches of practical court field to test our system. Since the tight recording burden had been indeed noticeably alleviated in their legal-action councils, the court staffs had endorsed that the proposed entire system could be a friendly labor-saving AI apparatus for on-line automatic multi-dialogue recording. © The Author(s), under exclusive licence to Springer science+Business Media,

The utilization of fifth-generation wireless technology (5G) and artificial intelligence (AI) has opened many paths toward making solar power utility systems run more efficiently. 5G and AI have emerged within the last couple of years as competent technologies that can be used in various settings, including within the field of utility delivery. The main concern about this is how these technologies should be used in renewable energy systems and to what extent they improve operations. This research work is about 5G-enabled solar power systems. One of the models used AI-based implementation, while the other does not. Data for both models pertained to parameters such as power, state of charge, harmonic distortion, and voltage are collected. The results are then compared to determine the effectiveness of using AI with the system. Analysis has shown that implementing AI technology with 5G in a solar power system greatly improves power efficiency by stabilizing the voltage of the model. Furthermore, integrating AI with this model has proven to show unparalleled accuracy compared to a version of the model that does not use AI. It can therefore be inferred that usage of 5G with AI technologies will generally be an improvement over solar power implementations that do not use them. © 2025 IEEE.

Social Spider Optimization (SSO) is a swarm algorithm, based on the mating and cooperating behaviour of social spiders. This approach is basically used for global optimum search during allocation of resources and data compression in Internet of Things (IoTs) networks. Some of the Swaram Intelligence (SI) algorithm such as Particle Swarm Optimization (PSO) algorithm, Ant Colony Optimization (ACO), Social Spider Optimization (SSO), Parallel Social Spider Optimization (PSSO) are numerically simulating to decrease computation time for resource allocation, to improve the energy efficiency and data compression rate in IoT networks. However, still some deficiencies exist in the system. To overcome these deficiencies, an Adaptive Social Spider Optimization (ASSO) algorithm is suggested for global search optimum. This proposed model will update the both the female and male individuals’ positions, and each individual position can be calculated during the search process. This will help to strengthen the ability of the search performance. ASSO has been compared with the existing algorithm to obtain experimental results that shows the suggested ASSO conquered better result with an allocation rate of 96.90% and consumed energy 0.6mj that is comparatively better than PSSO. © Bharati Vidyapeeth's Institute of computer Applications and Management 2024.

In this paper, we introduce EMD-Based Hyperbolic Diffusion Distance (EMD-HDD), a new method for constructing a meaningful distance metric for hierarchical data with latent hierarchical structure. Our method relies on hyperbolic geometry, diffusion geometry, and the Earth Mover's Distance (EMD). Specifically, our method embeds data points into a product manifold of hyperbolic spaces, allowing us to recover the hidden hierarchical structure encoded by the mutual relationships between features. We demonstrate the effectiveness of EMD-HDD through experiments on five hyperspectral imaging datasets, showcasing its capability to capture and reveal the intrinsic hierarchical structures inherent in such data. © 2025 IEEE.

Traditional backdoor attacks insert a trigger patch in the training images and associate the trigger with the targeted class label. Backdoor attacks are one of the rapidly evolving types of attack which can have a significant impact. On the other hand, adversarial perturbations have a significantly different attack mechanism from the traditional backdoor corruptions, where an imperceptible noise is learned to fool the deep learning models. In this research, we amalgamate these two concepts and propose a novel imperceptible backdoor attack, termed as the IBAttack, where the adversarial images are associated with the desired target classes. A significant advantage of the adversarial-based proposed backdoor attack is the imperceptibility as compared to the traditional trigger-based mechanism. The proposed adversarial dynamic attack, in contrast to existing attacks, is agnostic to classifiers and trigger patterns. The extensive evaluation using multiple databases and networks illustrates the effectiveness of the proposed attack. © 2020 IEEE.

Virtual memory systems rely on the page table, a crucial component that maps virtual addresses to physical addresses (i.e., address translation). While the Radix Page Table (RPT) has traditionally been used for this task, its limitations have become more apparent with the rise of memory-intensive applications. Recently, Hashed Page Tables (HPTs) have been explored as an alternative page table structure to offer faster address translation. However, the HPT introduces its own set of challenges particularly in resizing the page table and allocating contiguous physical memory space for storing the table. To tackle the fundamental problem of the existing HPT designs, this paper introduces Distributed Page Table (DPT), a novel approach that utilizes the physical memory as a huge hashed page table. DPT distributes Page Table Entries (PTEs) across the entire physical memory space, significantly reducing the hash collisions while avoiding the table resizing overheads. When distributing the PTEs across the physical memory, they can be mapped to memory locations already allocated to data pages. This new type of collision, referred to as address collision, may reduce the effectiveness of the DPT. This paper showcases that the DPT can effectively resolve the address collision with three simple yet efficient techniques: Strided Open Addressing (SOA), Collision-Aware Virtual Address Allocation (CVA) and Collided Page Displacement (CPD). Our experimental results demonstrate that DPT achieves average performance improvements of 12.6%, 11.6%, and 8.7% compared to traditional RPT, the latest large-coverage TLB design, and state-of-the-art HPTs, respectively. © 2024 IEEE.
