Research on backup and remapping of network slice based on security classification by Zhiyong SUN, Xinsheng JI, Wei YOU, Quan YUAN

“…In the future virtual environment of 5G core network,the general X86 servers make the attackers exploit vulnerabilities more easily,the substrate network is infected with and spreads the virus more easily,and the problem of single physical node failed will affect the service performance of the network slice seriously.Based on the existing node backup and remapping solutions,considering the impact of security constraints among nodes on network security performance,a security parameter evaluation model of virtual nodes and physical nodes were proposed in the network slicing,and the security constraint relationship was established between the virtual nodes and the physical nodes.Then backup virtual nodes were selected based on the security parameters evaluation model,and backup mapping methods were designed.Finally,the node remapping mechanism was designed with satisfying the requirement of network delay.Experiments show that the proposed method can significantly improve network intrusion tolerance with satisfying the requirements of network slicing service performance.…”

Optimization model of random load balancing of heterogeneous nodes in complex buildings by Wenlei GUO

“…In order to improve the load balancing of a complex building complex IoT and maintain its stable operation, a random load balance optimization model for non-uniformly distributed nodes in a complex building complex IoT was proposed.Sensor devices were deployed and wireless networks were accessed in complex building clusters to build the Internet of things for complex building clusters.The distribution location of each node in the Internet of things environment was determined, and random load data of non-uniformly distributed nodes was collected and integrated.The priority of non-uniformly distributed nodes was calculated using the IALBR routing protocol.By generating scheduling links and calculating the scheduling amount, the node load balancing scheduling task of the model was completed, and the load balancing of the Internet of things was optimized.The experimental results show that compared with traditional models, the average value of the load balance index of nodes under the design model is 0.002.The application of the design model effectively reduces the congestion probability of the Internet of things and improved network throughput.…”

Fast panoramic image stitching algorithm based on parameter regression by Fan GUO, Xiaohu LI, Wentao LIU, Jin TANG

“…In reality, the field of view of images acquired by cameras was usually limited, and the demand for panoramic images was increasing.Therefore, a fast panoramic image stitching algorithm based on parameter regression was proposed for panoramic image sequences.The traditional image registration task was transformed into deep learning combined with machine learning, a multi-scale deep convolutional neural network (MDCNN) based on Gaussian difference pyramid was designed to extract features of stitching images, and LightGBM regression model was used to predict stitching parameters.The transformation matrix and the focal length of the camera were obtained to align the images, and a hyperbolic image fusion algorithm was designed to eliminate the stitching seam between the images.The experimental results show that the proposed algorithm can quickly mosaic images and obtain clearer and more natural panoramic mosaic effects than the existing representative algorithms.It also has good adaptability for infrared images.…”

Research on Seismic Resistance of Precast Concrete Shear Walls with Bolt Splicing by XU Zhuang, ZHANG Ruigang

“…A design scheme of fully-assembled precast concrete shear walls with unit components spliced by bolts is proposed for the prefabricated unit residence system.An integral precast wall and two overlapped precast ones (consisting of two thin panels spliced horizontally by bolts) are designed,and low-cycle static loading tests of the walls under the bend-shear coupled loading mode are performed to study the seismic resistance of the structures.The research results indicate that the failure mode of the overlapped wall is the same as that of the integral one,and the crack development of the wall body is insufficient.The bearing capacity of the overlapped wall is equivalent to that of the integral one.The former is more ductile,whose displacement ductility factor is about 1.1 times that of the latter.The initial stiffness of the integral wall is larger than that of the overlapped one,but the former's stiffness degrades faster.In addition,the quantity and locations of bolts have little effect on the energy dissipation capacities of overlapped walls,and joint connection might be the only function of bolts for overlapped walls.…”

Logistic chaotic sequence generator based on physical unclonable function by Chunguang HUANG, Hai CHENG, Qun DING

“…Logistic nonlinear chaotic system has many good characters such as initial value sensitivity and topological mixing in the some parameter condition,which is used to create the random sequence signal generator.Because of the attributions of randomness and uniqueness even under the exact,the same circuit layouts and manufacturing procedures,there is still an instinct unclonable difference in each integrated circuit.Therefore,a new sequence stream generator was proposed based on Logistic chaotic system and physical unclonable function designed by double output look-up-table (LUT).The output of the Logistic sequence generator was associated with a specific physical circuit.This kind of sequence generator could resist an attack such as the replication of the keys of the system.The system was designed and tested on the Xilinx FPGA board.The results show that the same architecture of the circuit and the same config file operated on the different FPGA developing board can generate the total different random chaotic sequence stream and improve the randomness of the stream.…”

UAV deployment and caching scheme based on user preference prediction by Jiazhi REN, Hui TIAN, Shaoshuai FAN, Yuanzhuo LIN, Gaofeng NIE, Jilong LI

“…In order to design an efficient edge caching policy considering spatial heterogeneity and temporal fluctuations of users’ content requests,a proactive caching scheme was proposed with UAV’s deployment location design based on user preference prediction.Firstly,each user’s preference characteristics were predicted based on file similarity and user similarity,and the request time and user location were also predicted when a content request occurs.Thereafter,on the basis of the predicted geographical location,request time and user preference,each UAV’s deployment location and the corresponding content placement were determined by virtue of clustering method based on SOM and AGNES.Simulation results show that the proposed scheme outperforms other three comparison schemes in terms of hit ratio and transmission delay.Furthermore,the results also reveal that content preference is correlated with different user features by different weights.Accordingly,different impact weights should be matched with different user features.…”

Optimal structural similarity constraint for reversible data hiding by Jia-jia XU, Wei-ming ZHANG, Rui-qi JIANG, Neng-hai YU, Xiao-cheng HU

“…Most reversible data hiding (RDH) techniques have been evaluated by PSNR,which is based on MSE.Unfortunately,MSE turns out to be an extremely poor measure when the purpose is to predict perceived signal fidel-ity or quality.The structural similarity index has gained widespread popularity as an alternative motivating principle for the design of image quality measures.How to utilize the characterize of SSIM to design RDH algorithm is very critical.An optimal RDH algorithm under structural similarity constraint was proposed.Firstly,the metric of the structural similarity constraint was deduced.Secondly,the rate-distortion function of optimal structural similarity constraint was constructed,which was equivalent to minimize the average distortion for a given embedding rate.Fi-nally,the optimal transition probability matrix under the structural similarity constraint was obtained.Experiments show that the proposed method can be used to improve the performance of previous RDH schemes evaluated by SSIM.…”
