Community aware content retrieval in disruption-tolerant networks

Abstract

A major challenge in the design of a sparse mobile ad-hoc network (MANET) is the support of efficient content retrieval. Information-centric network (ICN) is an emerging network technology which provides a viable underlying architecture for efficient content distribution. However, current mobile ICN approaches generate excess control overhead that cause scalability issues as network and content sizes grow. In this paper, we propose a community-based content retrieval architecture which is highly scalable in disruption-tolerant mobile information-centric networks. Simulations in the NS-3 environment shows that our system requires less control overhead while maintaining comparable performance for content retrieval applications.
