Research on cloud manufacturing service architecture and consensus algorithm based on blockchain technology by Weijin JIANG, Wenying ZHOU, En LI, Tiantian LUO, Ying YANG

“…With the deep integration of information technology and manufacturing, the networking of manufacturing transactions has become an inevitable trend.Cloud manufacturing services can realize cross-supplier transactions that are not limited by geographical space, but in the process of transaction, there are problems such as difficulty in guaranteeing the trust of both parties and leakage of privacy.In order to solve the above problems, a cloud manufacturing service platform architecture based on a dual-chain model was proposed, which stores user data and transaction data in separate chains, and adopts a practical Byzantine fault tolerance (PBFT) consensus algorithm to solve the problem of data synchronization between blocks.However, traditional PBFT consensus algorithm has bottlenecks in storage and consensus efficiency, and is not suitable for large-scale manufacturing platforms.Therefore, further research on the PBFT consensus algorithm was carried out.The election process was optimized and the consensus protocol process of the consensus cluster was improved by combining the EigenTrust model and the quality of service (QoS), and then give the manufacturing resource rent-seeking and matching steps.Analysis and simulation experiments show that this research effectively improves the reliability of PBFT consensus nodes, improves the operating efficiency of the platform and the speed of block consensus, and saves data storage space.…”

Dynamic load balancing algorithm based on queuing theory comprehensive index evaluation by Wenbo WANG, Qingwei YE, Yu ZHOU, Zhihua LU

“…Internet communication,computer cluster and cloud environment have complex and dynamic characteristics,which can cause load imbalance easily,reduce the service efficiency and increase the energy consumption.Therefore,the load balancing technology becomes the focus of research.The existing load balancing strategy uses the occupancy of CPU,memories,processes to estimate the current load of each server.But it is hard to guarantee its accuracy.Aiming at this problem,a dynamic load balancing algorithm based on queuing theory comprehensive index evaluation was proposed.Firstly,queuing theory model was introduced to estimate the real-time load of each server,and then the tasks of input queue was distributed to each server separately according to the load comprehensive index of each server.Experimental results show that this method can balance the load of each server effectively and reduce the average waiting time of the task requests,which is of great application value.…”

LDPC code reconstruction based on algorithm of finding low weight code-words by Pei-dong YU, Hua PENG, Ke-xian GONG, Ze-liang CHEN

“…LDPC code reconstruction without a candidate set is one of the tough problems in channel code reconstruction.First,theoretical analysis was provided for the number of received code-vectors needed for the reconstruction,and a lower bound was derived.Then,according to the lower bound,and based on an algorithm for finding low weight code-words,a new reconstruction method was proposed.It looked for low weight vectors one by one from the dual space of the received code-vector space and used them to reconstruct the sparse parity-check matrices.Number of iterations and the computational complexity of the method were analyzed based on exponential distribution theory.Under noise-free conditions,drawbacks of the existing method,including limited applicable range and large quantity of required data,have been overcame.Under noisy conditions,the proposed method has higher robustness against noise and relatively low complexity,compared to existing methods.For QC-LDPC codes,the reconstruction performance can be further improved using the quasi-cyclic property of their sparse parity-check matrices.…”
