A Preliminary Study on the Impact of User's Sociality on Content Caching of ICN

In this letter, we consider socially-aware ICN (Information-Centric Networking) and empirically reveal the impact of user's sociality, which is corresponding to human factors on social media, on the content caching of ICN. To this end, among user's sociality, we focus on the information propagation behavior and the community structure, and describe a sociality-aware ICN model incorporating these two sociality. Also, we investigate the impact of these two sociality on the performance of ICN. Our key finding is, for instance, that the effectiveness of cache is significantly affected by the community structure rather than the information propagation behavior.
