摘　　要：为解决移动网络中存在的海量视频数据重复传输的问题,基于设备直连技术设计了一种本地缓存共享系统。在系统设计中,综合考虑视频对用户的吸引程度异构性和不完全的分享意愿,利用泊松点理论对移动数据特征进行了建模分析。在服务供应商和网络用户之间,考虑社交关系,针对资源分享建立了交易模型。实验结果表明,D2D本地缓存系统可以有效降低数据传输延迟,提高供应者的服务质量和网络视频用户的满意度。In order to solve the problem of repeated transmission of massive video data in mobile networks,a local cache sharing system is designed based on device direct connection technology.In the system design,comprehensively considering the heterogeneity of video attraction to users and the incomplete willingness to share,the Poisson point theory is used to model and analyze the characteristics of mobile data.Considering social relationships between service providers and Internet users,a transaction model is established for resource sharing.The experimental results show that the D2D local cache system can effectively reduce the data transmission delay,and can improve the service quality of service providers and the satisfaction of network video users.
