Intelligent prediction method of network performance based on graph neural network
Published 2022-03-01“…There are some problems in the traditional network performance prediction technology, such as incomplete network state acquisition and poor accuracy of network performance evaluation.Combined with the characteristics of graph neural network learning and reasoning network relational data and the captured global information of the network, on the basis of the current network performance prediction methods, an intelligent prediction method of network performance based on graph neural network was proposed.Aiming at the complex network information, through the research of network system abstraction and network performance modeling, the network information can be transformed into the graph space convolution was used to process the message passing process of graph network nodes to realize the relationship reasoning between network information.The graph neural network model for network performance prediction was studied, and a graph neural network architecture which could deal with traffic matrix, network topology, routing strategy and node configuration was proposed.Finally, the experiments show that the model can better achieve accurate prediction of the network performance including delay, jitter and packet loss rate.…”

Regulation of Th1/Th2 cells in asthma development: A mathematical model
Published 2013-05-01“…In the present workwe representthe complex network of interactions between cells and molecules by a mathematical model.The model describes the behaviors of cells (Th0, Th1, Th2 and macrophages)and regulatory molecules (IFN-$\gamma$, IL-4, IL-12, TNF-α) in response tohigh, intermediate, and low levels of LPS.The simulations show howvariations in the levels of injected LPSaffect the development ofTh1 or Th2 cell responses through differential cytokine induction.The model also predicts the coexistence ofthese two types of responseunder certain biochemical and biomechanical conditions in the microenvironment.…”

V2X offloading and resource allocation under SDN and MEC architecture
Published 2020-01-01“…To address the serious problem of delay and energy consumption increase and service quality degradation caused by complex network status and huge amounts of computing data in the scenario of vehicle-to-everything (V2X),a vehicular network architecture combining mobile edge computing (MEC) and software defined network (SDN) was constructed.MEC sinks cloud serviced to the edge of the wireless network to compensate for the delay fluctuation caused by remote cloud computing.The SDN controller could sense network information from a global perspective,flexibly schedule resources,and control offload traffic.To further reduce the system overhead,a joint task offloading and resource allocation scheme was proposed.By modeling the MEC-based V2X offloading and resource allocation,the optimal offloading decision,communication and computing resource allocation scheme were derived.Considering the NP-hard attribute of the problem,Agglomerative Clustering was used to select the initial offloading node,and Q-learning was used for resource allocation.The offloading decision was modeled as an exact potential game,and the existence of Nash equilibrium was proved by the potential function structure.The simulation results show that,as compared to other mechanisms,the proposed mechanism can effectively reduce the system overhead.…”
