Abstract

The ever increasing demand for content is straining operators’ networks, which encourages the development of content delivery mechanisms. Mobile edge caching and device-to-device technologies constitute a promising solution for reducing the effects of demand growth by placing popular content files in proximity to uses. Mobile Edge caching enables users obtain the requested contents from small cellular or other user equipments, rather than the content server through the mobile core networks, so as to alleviate the bottleneck of backhual in 5G network and reduce the delay. In this paper, we simulate the caching scenario in 5G networks by fusing with content centric network using OPNET Modeler, the obtained simulation results show that edge cache and local D2D cooperative cache can achieve higher hit rate, effectively reduce the delay of users' access to content, and reduce the core network traffic of 5G.
