Social network resource allocation method based on SRM algorithm

Abstract

The invention discloses a social network resource allocation method based on an SRM algorithm, and provides a community clustering model aiming at minimizing weighted interference by fully consideringthe characteristics of D2D communication in a physical domain and a social domain. Under the condition that no file cache is required in a system, a base station firstly sends a file to a wireless access point through a wired link, then the wireless access point sends the file to a source node of each community cluster through a wireless network, and finally the source node sends the file to eachmobile user in the cluster in a D2D communication mode. The problem of community clustering among mobile users is solved through a spectral clustering algorithm, and on the basis, a one-to-one resource allocation method for cellular communication and D2D communication is designed by adopting a matching algorithm according to the stable throughput in a community. According to the invention, the transmission throughput of the system can be greatly improved, the load of the base station is reduced, and the overall performance of a cellular communication system is further optimized.

Description

technical field [0001] The present invention relates to the field of D2D communication, in particular to a community clustering and resource allocation method of a social network based on an SRM algorithm. Background technique [0002] With the rapid popularization of smart terminal devices, we have witnessed the explosive growth of communication capabilities of wireless communication systems in the past decade. The great-leap-forward progress of mobile communication technology has made people's social networking transition from traditional social networking sites to mobile networks, and the inextricable social relationships among mobile users have woven into a huge mobile social network. The formation, evolution and development of mobile social networks provide people with a more convenient communication platform, making communication between people more quality and more efficient, while saving material time costs. Nowadays, social networks have become an important part of...
