LeafPopDown: Leaf Popular Down Caching Strategy for Information-Centric Networking

Information-Centric Networking is a name based internet architecture and is considered as an alternate of IP base internet architecture. The in-network caching feature used in ICN has attracted research interests as it reduces network traffic, server overload and minimizes latency experienced by end users. Researchers have proposed different caching policies for ICN aiming to optimize performance metrics, such as cache hits, diversity and eviction operations. In this paper, we propose a novel caching strategy of LeafPopDown for ICN that significantly reduces eviction operation and enhances cache hits and diversity in ICN.
