Abstract

The invention discloses a method for caching social content in an edge network area. In each time slot, all users in the edge network area are subjected to the following steps: the first step: constructing a set of candidate content; the second step: predicting the candidate content The regional popularity index of each content in the collection; the third step: predict the user's regional transfer probability; the fourth step: obtain the income that each content in the candidate content set will get if it is cached according to the regional popularity index and the user's regional transfer probability ratio; the fifth step: randomly select the corresponding content from the candidate content set with the probability of the revenue ratio for caching.

Description

technical field [0001] The invention relates to a social network, in particular to a social content caching method in an edge network area. Background technique [0002] The rise of online social networks, the popularization of smart devices, and the development of wireless communication technologies have had a great impact on the content acquisition mode of users in edge networks. Due to the uneven distribution of popularity of social content, according to the traditional content distribution method, caching the content generated by users to the edge server will cause a serious waste of bandwidth and storage resources. The spread of massive social content among mobile smart device owners through social connections urgently requires a new content distribution method to improve the performance of the entire distribution system. [0003] At the same time, with the development of device-to-device communication technology, it becomes possible to directly exchange content betwee...
