Performance Evaluation of Content Caching in CoMP enabled-Small Cell Networks

Junseop Ahn and Hong-Shik Park
Abstract—In this paper, we present a detailed comparison of two content caching strategies in the case of Coordinated Multi-Point (CoMP) enabled small cell networks: Probabilistic Randomized Caching (PRC) and Popular Content and Content Diversity based Caching (PC + CDC). We analyze the effect of hit ratio assisted by CoMP according to cache size, content popularity distribution, and small cell base station (SBS) density. Our analysis shows that hit ratio of caching with CoMP outperforms that of caching without CoMP and PC + CDC shows better performance in the given cache size, content popularity distribution, and SBS density. In particular, we can infer that the content popularity distribution and cache size are influential factors for increasing hit ratio of caching in CoMP enabled small cell networks and SBS density and content diversity based caching strategy are significant factors for better hit ratio gain in CoMP scenario.

Index Terms—Small cell networks, cooperation, CoMP, probabilistic randomized caching, and popular content and content diversity based caching.
