Dynamics of substrate resource selection in network virtualization environment——an evolutionary game approach by Yu YANG, Shan-zhi CHEN, Xin LI

“…The substrate network path selection problem of virtual network was modeled as an evolutionary game.In the process of evolutionary game,virtual networks adjusted the strategies through the iterated game.The replicator dynamics were leveraged equation to analyze the dynamic variation of strategies selection and demonstrates that this dynamics equation is the admissible dynamic to the evolutionary game.The potential game theory was used to analyze the evolutionary process and demonstrates the evolutionary result will converge to the evolutionary equilibrium.At the evolutionary equilibrium,all the virtual networks could get the best selection strategies.Finally,an evolutionary algorithm based on replicator dynamics was proposed.The experiments simulate the process of virtual network selecting the substrate paths in different initial state and reach the evolutionary equilibrium.Simulation results are coincided with the theoretical analysis results.…”

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.…”

Public opinion model based on super-influencer integrating network community and content by Jianliang WEI, Hao JI, Tengyan TIAN, Shengli ZHOU

“…Aiming at the abnormal deviation and distortion of online public opinion,a public opinion model based on super-influencer integrating network community and content was designed.Deffuant-Weisbuch (DW) model was adopted,and factors such as user relationship,node identity and information noise were incorporated into the model,and the generation of public opinion deviation was simulated through simulation experiments.The results indicate that super-influencer leads to irreversible deviation of network public opinion,controversial content causes opinion fluctuation and convergence,but not the final opinion as a whole.There are differences in the interference effect between strong and weak communities,and by increasing the internal strength and external influence of the community,it can conduct public opinion confrontation with super-influencer,thus reversing the direction of public opinion deviation.…”

Transmission characteristics of air-ground channel in aerial communication platform by Xiaobin FU, Baohui ZHENG

“…Satellite communication can solve the problem of global communication,at the same time,it follows the problems of difficult deploy and limited satellite resources.Aerial communication platform is consisted of aircraft with payload communication and not more than 10 km from ground.The platform communicating with ground nodes can solve the weakness of traditional satellite communication.The loss of air-to-ground channel was analyzed to model the air-to-ground wideband channel in Ku and Ka band.The consequence of theory and simulation demonstrates that the fading of the model has serious influence on transmission performance.In low elevation transmission,the value of K-factor is small because of multipath reception.Simulation results show that orthogonal frequency division multiplexing (OFDM) can be a good candidate for wideband communications to transmit payload data from aerial platform to ground station.…”

Performance analysis and re-modeling of secondary users in cognitive radio system by Wei LIN, Yu FU, Qin-yu ZHANG, Ye WANG, Sheng WANG

“…A number of errors in the past Markov model and theoretical analysis were discussed in spectrum access based on cognitive radio network (CRN).To imitate the behav ary user (PU) and secondary user (SU) factually,new models for access strategy were presented.The performance of CRN based on different access strategies were reappraised and compared by using matrix geometric theory and event scheduling of discrete events system simulation.Theoretical analysis results and simulation experiments were tally close,which confirms the reliability of proposed models.The access strategies with handoff and channel reservation efficiently decrease the call dropping probability,as while as,increase the blocking probability.And the thought for CRN can reach the maximum in the latter with the optimum number of reserved channels.…”
