In edge computing, the Zero-Trust Security Model (ZTSM), as a key enabling technology for next-generation networks, plays a crucial role in providing authentication for addressing data sharing concerns, such as frequent data breaches, data misuse, and cyberattacks. However, due to the complexity and diversity of edge environments, ZTSM struggles to meet the security requirements of data sharing frameworks solely through enhanced authentication. Consequently, such frameworks with ZTSM still face challenges in ensuring data integrity, evaluating various node behaviors, and coping with the increasing complexity of node attributes. To address these issues, we propose a blockchain-enabled secure, fair and scalable data sharing framework in a zero-trust edge-end environment in this paper. Specifically, we first propose a Merkle forest-based data storage model for the classified storage of loosely coupled data, consequently enhancing the scalability of the model. Then, we design a node behavior-based reputation assessment mechanism to ensure fairness during data sharing. Moreover, a data sharing protocol supervised by smart contract is proposed, working with the aforementioned storage and assessment schemes, to ensure the security of data sharing. Finally, comprehensive security analysis validates the security, fairness and scalability of the proposed framework. Extensive experimental results show that, as transaction volume grows, the time cost of data traversal in the storage model becomes progressively more efficient. Additionally, when the size of the smart contract is increased tenfold, the maximum time cost of the data sharing protocol rises by only 4.98 times. © 1983-2012 IEEE.

With the expansion of IoT application scenarios, the demand for edge IoT devices with integrated video analysis capabilities is gradually increasing. In remote areas where cellular base stations cannot reach, a low-cost wireless communication self-organizing network is urgently needed to transmit video processing results and images. LoRa has strong anti-interference performance and relatively high transmission rate, which is suitable for completing delay-tolerant information transmission. However, the traditional LoRaWAN protocol has low efficiency in image transmission. This paper proposes a multi-packet transmission communication protocol based on LoRa, which reduces the time for traditional communication protocol confirmation and processing, and focuses more on the image transmission of LoRa. Experimental results show that the multi-packet transmission protocol achieves relatively high communication efficiency. © 2023 IEEE.

The number of Internet of Things (IoT) devices in the world has grown to 43 billion in 2023. With the expansion of the IoT industry, the types and communication protocols of IoT devices are also increasing. In the actual deployment of the Internet of Things, it is more complicated and difficult to develop a truly interconnected IoT platform in the face of a variety of IoT devices. At the same time, the increasing number of devices has brought great challenges to the high availability of the platform. We designed and implemented a multi-protocol access method for the IoT platform, which can configure public and private protocols according to requirements, and make up for the shortcomings of the current IoT platform in device access. In order to ensure the availability of the platform, the container dynamic scheduling method is generally adopted when the sudden high load demand is needed. However, due to the time-consuming operation in the container scaling process, the existing container scheduling method cannot immediately meet the load demand. We proposed a combined prediction model based on LSTM and RELM, and proposed a container dynamic scheduling strategy based on load prediction. This scheduling strategy is applied to the multi-protocol access method to ensure the stability and availability of the access process. Finally, the multi-protocol access method is tested. The results show that this method can ensure the access of multi-protocol IoT devices. The reliability test shows that it has good performance and meets the current demand for IoT platforms. In addition, the strategy of this paper is compared with other strategies to further verify the rationality and availability of the method. © 2023 IEEE.

Deformation monitoring data can most intuitively reflect the current movement process of the landslide and is likewise the most essential and effective warning feature of the landslide warning model. To solve the current problem that it is difficult to identify the uniform deformation phase and adjust it dynamically in time, which leads to the high false alarm and leakage rate of the early warning algorithm, we adopt the Pauta criterion and the Lagrange interpolation method fused with the improved adaptive Kalman filter to improve the accuracy of the original monitoring data, propose a real-time determination method of uniform deformation phase based on statistical analysis, and construct a process-oriented dynamic early warning algorithm by examining the normal distribution of the second-order derivative values of the cumulative displacement curve and the changing trend of the linear regression coefficient of determination. The experimental results show that the research method can effectively reduce the abnormal fluctuation interference of data, accurately discriminate the uniform deformation phase, improve the early warning accuracy of the creep tangent angle warning model, and has excellent application value for the subsequent realization of systematic and automated real-time monitoring and warning. © 2023 IEEE.

Hartmann wavefront sensor is applied widely in adaptive optics systems. Considering the real-time performance requirements and processing amount of Hartmann sensors in computing the centroids of points, this article proposes an FPGA-based real-time image processing and centroid extraction system. The system adopts FPGA as the core processor and uses the connected domain labeling algorithm and the gray centroid method to complete the centroid calculation. In addition, the calculation results are output simultaneously through multiple DAs to drive the device under test to achieve image wavefront restoration. At the same time, the image data is uploaded to the host computer in real-time through the Ethernet interface. The system has excellent performance in real-time image processing, image output quality, and system control stability. Experiments show that it is an efficient technical means of providing real-time wavefront processing measurement for the Hartmann sensor in various application scenarios, such as adaptive optical correction. © 2023 IEEE.

Reconstructing urban traffic dynamics in three dimensions is crucial for effective traffic management. However, current research often neglects the posture and shape reconstruction of vehicles within traffic scenes. This paper introduces GAPSR, an innovative method addressing the challenge of monocular 3D pose and shape reconstruction, with a focus on vehicle-related information. Utilizing graph networks, our approach extracts unstructured logical topological features to enhance the expressiveness of 2D features. Attention prediction modeling is then introduced, considering the correlation between detected objects and vehicle shapes, as well as the scene context and road environment. In summary, our proposed method advances monocular 3D pose and shape reconstruction, as evidenced by experiments demonstrating its effectiveness across diverse datasets. This work provides substantial support for future research in traffic scene understanding and autonomous driving. © 2023 ACM.

Most of the current existing style transfer methods are based on photographs or Western paintings. Due to the inherent differences between Chinese and Western paintings, direct application of existing algorithms cannot generate satisfactory style transfer results for Chinese ink paintings. Accordingly, I propose a new feedforward style transfer method [1], called inkStyle, which uses a draw Network to transfer global style patterns at low resolution and a higher resolution details Networks to modify local style patterns in a pyramidal manner based on the multi-level Laplacian filtering output of the content image. The experimental results show that the method in the paper performs better and produces better visual results. © 2023 SPIE.

Assessing data quality through Functional Depen-dencies (FDs) is a crucial aspect of data governance. However, with the diverse range of data sources and the exponential growth in data volume, exact FDs can sometimes be impractical for real-world applications. In contrast, relaxed functional dependencies (RFDs), which allows for some flexibility in attribute value comparisons, demonstrates greater adaptability and flexibility for big data scenarios. To address the efficient discovery of RFDs, this paper proposes a novel mining method to supplement the current research gaps. By establishing a difference table for tuples, we transform the problem into a specialized minimal set covering problem. Additionally, we introduce two optimization strategies: reducing the time complexity of enumerating the left-hand side of the base RFDs to 0 (1) and decreasing the search complexity for feasible LHS attributes and threshold candidates from O(2m-l) to O(1.5m-1). We rigorously proof that our mining approach guarantees the identification of validity and minimal RFDs. Experiments on nine real-world datasets reveal that our method significantly improves efficiency compared to existing techniques. Furthermore, it uncovers more concise and higher-quality RFDs. Importantly, the RFDs extracted through our methodology exhibit better performance in downstream cleaning tasks. © 2024 IEEE.
