物联网下网络视频丢包率到用户体验质量的数学映射模型

Mathematics Mapping Model of Network Video Packet Loss Rate and the Quality of Experience under the Internet of Things

物联网和网络视频丢包率到用户体验质量的映射模型是学术界和工商界的热点话题。为了研究视频在网络传输过程中丢包对QoE的影响并建立丢包率到QoE的映射,搭建了NS2 + MyEvalvid实验仿真平台,重点研究丢包对用户体验质量QoE的影响并建立丢包率到用户体验质量QoE的映射。仿真结果表明,丢包对用户体验质量QoE有着显著影响,丢包率和用户体验质量QoE呈现一元非线性关系。因此,在研究丢包对QoE有显著影响的基础上,采用一元非线性回归分析的方法建立丢包率到用户体验质量QoE的映射。

The mapping model of the network and network video packet loss rate to the quality of user expe-rience is a hot topic in the academia and the industry and commerce.In order to study the influence of packet loss on QoE and establish the Mapping model of packet loss rate and the Quality of experience when the video transmits in the network,this paper builds an NS2+MyEvalvid simula-tion platform,focuses on the influence of packet loss on QoE and establishes the Mapping model of packet loss rate and the Quality of experience.Simulation results show that packet loss has a sig-nificant influence on Quality of experience.Packet loss rate and the Quality of experience present a nonlinear relationship.Therefore,based on the study,packet loss has a significant influence on Quality of experience,using a nonlinear regression analysis method to establish the Mapping model of packet loss rate and the Quality of experience.
