A dominating-set-based and popularity-driven caching scheme in edge CCN

In this paper, we try to design a collaborative caching scheme in an edge Content Centric Networking (CCN). Specifically, we first decompose the arbitrary network into clusters based on dominating set. Then, we place the content heterogeneously within each cluster based on the content popularity results and resort to a dynamic request routing. Simulation results show that the proposed outperforms the existing caching mechanisms in CCN.
