Abstract(in English) In recent years, with the rapid growth of SNS (Social Networking Service), e.g., Twitter and Facebook, the amount of user-generated contents has dramatically increased. In addition, the amount of traffic for text and video data is increasing due to the active interaction among SNS users. One of promising network architectures to realize highly-efficient content delivery in SNS is {em cache network}, e.g., CDN (Content Delivery Network) and ICN (Information-Centric Networking). In order for the cache network to effectively operate, the key is to appropriately design the caching strategy and the cache-replacement algorithm at caching nodes, e.g., cache server in CDNs and router in ICNs. However, it is necessary to sufficiently consider various factors of a social network representing the social relationship among SNS users. Therefore, in this paper, we assume that ICN is introduced as a content distribution infrastructure for SNS, and extensively analyze the characteristics of the socially-aware ICN. In particular, we focus on the influential user called {em influencer}, which is one of typical features of social networks, and investigate the effect of the selection method of influential users and their ratio on the content caching in ICNs. Consequently, we reveal that the cache hit ratio differs significantly according to centrality measures that determine influential users, and that the cache hit ratio can be significantly improved by appropriately determining the ratio of influential users.
