Abstract

The invention discloses a social content caching method in an edge network area. The following steps are performed on all the users in the edge network area at each time slot. The steps comprises of a first step, constructing a candidate content set; a second step, predicting an area popularity index of each content in the candidate content set; a third step, predicting a user area transition probability; a fourth step, acquiring a cost benefit ratio obtained if each content in the candidate content set is cached according to the area popularity index and the user area transition probability; a fifth step, taking the cost benefit ratio as a probability and randomly selecting the corresponding content to carry out caching from the candidate content set.

Description

Technical field [0001] The present invention relates to social networks, in particular to a method for caching social content in edge network areas. Background technique [0002] The rise of online social networks, the popularization of smart devices, and the development of wireless communication technologies have had a greater impact on the mode of user access to content in edge networks. Due to the uneven distribution of the popularity of social content, if user-generated content is cached on the edge server according to the traditional content distribution method, it will cause a serious waste of bandwidth and storage resources. The dissemination of massive social content among mobile smart device owners through social connections urgently requires a new type of 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 exc...
