sNDN: A Social-aware Named Data Framework for Cooperative Content Retrieval via D2D Communications

Content Provider	ACM Digital Library

Abstract	In this paper, we advocate cooperative content retrieval, a novel and content-centric service paradigm via device-to-device (D2D) communications to reduce cellular traffic volume and to facilitate user wireless connectivity in mobile networks. By leveraging the Named Data Networking (NDN) principle, we propose sNDN, a social-aware NDN framework to achieve efficient cooperative content retrieval. Specifically, sNDN introduces Friendship Circle by grouping a user with her close friends of high physical proximity and content similarity. We construct NDN routing tables conditioned on Friendship Circle encounter frequency to navigate content requests and content deliveries between Friendship Circles, and leverage social properties in Friendship Circle to search for the final target as inner-Friendship Circle routing. The evaluation results demonstrate that sNDN outperforms other content retrieval schemes significantly.
