Method and device for social network collaborative caching based on user interest similarity

Abstract

The present invention provides a social network collaborative caching method and device based on user interest similarity, including: acquiring interest preference information of N user nodes; clustering N user nodes according to the interest preference information of N user nodes to obtain L user clusters; obtain the popularity of M network content; count the topological impact factors of N user nodes; complete the cache operation for the interest packets used to request data and the data packets corresponding to the interest packets passing through N user nodes according to the cache strategy , the caching strategy includes: the first area is used to cache the network content requested by the user node, the second area is used to cache the most popular network content in the social network, and the third area is used to cache users passing through the user node with a preset probability The network content requested by other user nodes in the user cluster where the node is located. The social network collaborative caching method and device based on user interest similarity provided by the present invention improve the cache hit rate.

Description

technical field [0001] The present invention relates to computer network technology, in particular to a social network collaborative caching method and device based on user interest similarity. Background technique [0002] A social wireless network is a network composed of a large number of wireless smart devices. It is a network with certain characteristics physically gathered by electronic communication devices such as smart phones, tablet computers, or e-book readers. Members in a social wireless network have similar or Same web content needs. With the rapid development of smart terminal devices and the development and use of a large number of terminal applications, users' demand for data is increasing, which also leads to the rapid growth of network traffic. Users of social networks often have more data requirements than the limited bandwidth provided by social networks. Therefore, how to improve the efficiency of network content distribution through content sharing ha...

AI Technical Summary

Problems solved by technology

[0004] With the existing technology, since the cache space of each electronic communication device in the social network is limited, when the amount of content that the user is interested in is greater than the size of the cache space of the electronic communication device, the hit rate of the cache is not high
