EdgeTouch Caching Strategy for Video on Demand Data Contents in Named Data Networking

Named data networks (ndns) agree to cache contents inside the network in order to offer efficient delivery of requested data. the recent works on in-network cache intent to focus on minimizing the homogeneous content to be cached for the betterment of the cache hit ratio, which could not show the way to save considerable bandwidth. on the other hand, the caching of the same content at more locations projected low diversity. moreover, it will increase the frequent caching operations, i.e., cache placement and replacement, causing supplementary power consumption, which should be kept away from energy-limit in data delivery environments, e.g., wireless networks. in this paper, a content disseminated caching strategy alongside the data routing path called edge touch caching strategy (etcs) is proposed. the main goal of etcs is to reduce the caching of homogeneous contents at numerous locations during data dissemination along the data delivery path to increase content diversity. this research also captured the effect of the cache hit ratio through a comparison between the etcs caching strategy with several state-of-art caching strategies in ndn. the results show that the etcs strategy can increase the content diversity along with the cache hit ratio even for different cache size it performs better than the existing state of the art strategies.
