Summary:Summary Information Centric Networking (ICN) is a novel future network architecture that is focusing on content distribution. Its ubiquitous caching schemes can improve network performance. In this paper, we propose a node importance to community based caching scheme with network coding in ICN, which is named as NICNC. For each community, content router makes cache decision depending on its node importance to community to make content cached more reasonable in temporal and spatial distribution. Moreover, by applying network coding into ICN, one coded blocks containing information of multiple chunks can satisfy multiple interests for different chunks sent by different consumers. This can significantly enhance cache diversity and cache hit rate without increasing cache capacity. Experimental results show that our scheme can improve the network performance at many aspects, such as average download time, cache hit rate, and instantaneous hop reduction rate.
