基于内容流行度的移动CCN缓存策略研究
Mobile CCN cache strategy based on content popularity
摘要
Abstract
Recently,in order to adapt to the shift from the sender-driven end-to-end communication mode to the receiverdriven mass content acquisition mode for Internct applications,and provide native support for scalable and efficient content acquisition from the network architecture level,researchers have proposed a content-centric networking (CCN),which has great potential to better support content distribution in the future Intemet.With the increasing number of mobile users,future mobile users will also visit the CCN.For user mobility in CCN,a mobility caching strategy based content popularity is proposed.This strategy considers user mobility,uses semi Markov model to model the mobility of users,and also uses multiple linear regression theory to predict content popularity.It combines with the user mobility and the original content popularity to derive a mobility cache strategy.Simulation results show that the addition of mobility will have a greater impact on the popularity of the content,and this strategy can effectively improve the cache hit rate.关键词
