Study on I/O response time bounds of network storage systems by CUI Bao-jiang1, LIU Jun2, WANG Gang2, LIU Jing2

“…In order to predict and improve the performance of networked storage systems,the relationship was explored between the system I/O response time and its performance factors by quantitative analytical method.Through analyzing data flow in networked RAID storage system,we established its analytical model utilizing closed queuing networks and studied on performance bounds of the system I/O response time.Experimental results show that the theoretical bounds are found to be in agreement with the actual performance bounds of the networked RAID storage system and reflect the dynamic trend of its actual performance.Furthermore,we conclude that the CPU processing power and cache hit rate of the server at the storage center are the key factors affecting the I/O response time,as the concurrent jobs are lower.…”

Privacy protection scheme of DBSCAN clustering based on homomorphic encryption by Chunfu JIA, Ruiqi LI, Yafei WANG

“…In order to reduce the risk of data privacy leakage in the process of outsourced clustering, a privacy protection scheme of DBSCAN clustering based on homomorphic encryption was proposed.In order to encrypt the float data in the actual scene, three data preprocessing methods for different data accuracy were given, and a policy for choosing a proper data preprocessing method based on data characteristics, accuracy and computational cost was also proposed.For the ciphertext comparison operation that was not supported by homomorphic encryption, a protocol between the client and the cloud server was designed to realize the function of ciphertext comparison.Theoretical analysis and experimental results show that the proposed scheme can ensure the security of data privacy, and has a higher clustering accuracy rate and lower time overhead.…”

Multicast resource allocation scheme considering source-coding characteristic in OFDM systems by XU Wen-jun, HE Zhi-qiang, NIU Kai, LIN Jia-ru, WU Wei-ling

“…Aiming to solve the problem that unicast or conventional multicast was incapable of make full use of the opening for wireless propagation in orthogonal frequency division multiplexing（OFDM） systems,a resource allocation scheme involving several multicast groups was proposed to maintain proportional fairness among groups.The proposed scheme consisted of subcarrier assignment algorithm and power allocation algorithm.The former was achieved by modi-fying the existing unicast subcarrier assignment algorithm,whilst optimal power allocation on condition that subcarrier assignment was determined was reached by the latter based on theoretically derived non-linear equations.Simulation re-sults show that the proposed scheme can ensure perfect fairness among different multicast groups,and remarkably out-performs conventional multicast in terms of rate-sum capacity.Combined with the low complexity,it is suitable for the application to voice/video multicast in actual wireless systems.…”

Performance comparison of systematic polar code and non-systematic polar code by Hui LI, Ming YE, Qiang TONG, Jie CHENG, Lijie WANG

“…Polar code in channel coding schemes is a research hotspot in 5G communication field.Polar code is susceptible to error propagation under successive cancellation decoding,and the performance of the code at short and medium block lengths is not ideal.For the problems,the performance difference between systematic polar code and non-systematic polar code was studied under various simulation conditions.Simulation results demonstrate that systematic polar code has advantage over non-systematic polar code in bit error rate performance,and the former are more robust against error propagation than the latter under successive cancellation decoding.The above results are considerable importance from the theoretical values in 5G communication and performance optimization of polar code.…”

Optimal configuration algorithm for static segment of FlexRay by Yong XIE, Ren-fa LI, Hua-bin RUAN, Xin PENG

“…FlexRay,which could provide high data bandwidth,time determinism and reliability,was recognized as the standard of the next generation automotive buses,but the complexity of the configuration hindered its wide application in automotive electronics systems.Slot ID assignment of static segment was the key part of its configuration.Started from the system-level point of view,a new system-level scheduling unit model was defined.Based on confining the iable slot IDs and analyzing delay for each scheduling unit,a branch and bound-based searching was carried on to search the optimal slot ID assignment plan that realized the minimization of system’s end-to-end delay.Both theoretical proving and experimental results show that the slot ID assignment method is optimal in optimizing system’s end-to-end delay.…”
