Content distribution over content centric mobile social networks in 5G

Abstract

Due to the rapid growth of network traffic and new demands from mobile users, the current mobile social networks face challenges in dealing with a huge amount of content requests, high operating costs, and mobility control. How to design mobile social networks efficiently for the upcoming 5G era has become an important issue. In this article we propose and outline a framework of content centric mobile social networks for 5G. First, we present a content centric based network architecture consisting of mobile users, communities, content centric nodes, small cells, and macro cells. Next, we discuss the detailed process to deliver mobile content based on the interests of content and mobile users. In addition, a novel caching scheme is presented to store replicas of mobile content, and the related experiment results are also given.
