Inter-Satellite Cooperative Computing Scheme Driven by Business Graph in LEO Satellite Network
Published 2021-06-01“…Low earth orbit-satellite network (LEO-SN) has the advantages of wide coverage and short satellite-to-earth link, and has become a current hot research fi eld.A business graph-driven inter-satellite collaborative computing method in LEO-SN was proposed to solve the problem of high transmission delay when the task was offl oaded to the cloud computing center.This method shielded the dynamics of LEO-SN by relying on the weighted time expansion graph model, combined multiple satellite computing resources, and dispatches tasks in the form of a directed acyclic graph to the satellites in the transmission path, thereby realizing the "computing while transmitting” of user services in the satellite cluster.The simulation results showed that when the data volume was 5 MB, the latency performance of on-orbit collaborative computing was improved by 58.9% compared to ground cloud computing.…”

Cell-phone origin identification based on spectral features of device self-noise
Published 2017-01-01“…With the widespread availability of cell-phone recording devices and the availability of various powerful and easy-to-use digital media editing software,source cell-phone identification has become a hot topic in multimedia forensics.A novel cell-phone identification method was proposed based on the recorded speech.Firstly,device self-noise (DSN) was considered as the fingerprint of the cell-phone and estimated from the silent segments of the speech.Then,the mean of the noise's spectrum was extracted as the identification.Principal components analysis (PCA) was applied to reduce the feature dimension.Support vector machine (SVM) was adopted as the classifier to determine the source of the detecting speech.Twenty-four popular models of the cell-phones were evaluated in the experiment.The experimental results show that the average identification accuracy and recall of the method can reach up to 99.24% and demonstrate that the self-noise feature has more superior performance than the MFCC feature.…”
