Caching strategy based on node’s importance to community in information-centric networks
In-network caching is one of the most important features of ICN (information-centric networks).A caching strategy based on node’s importance to community was proposed to make content objects cached more reasonable in temporal and spatial distribution.Within each community,the strategy not only cache...

| description | In-network caching is one of the most important features of ICN (information-centric networks).A caching strategy based on node’s importance to community was proposed to make content objects cached more reasonable in temporal and spatial distribution.Within each community,the strategy not only caches content objects in those nodes where users are easy to access the content,but also makes different popularity of content objects more reasonable in temporal distribution.The CSNIC strategy was implemented under a variety of experimental conditions,and compare it with the previous strategies CEE-LRU,Betw-LFU and Opportunistic.The simulation results show that the strategy can yield a significant performance improvement,such as,cache hit ratio,hop reduction ratio,content diversity ratio and number of replacement.Furthermore,the additional overhead of CSNIC is small. |
