Edge Computing-Induced Caching Strategy for National Traditional Sports Video Resources by Considering Unusual Items

In order to promote the development of national traditional sports to carry forward the spirit and culture of a country or nation, this paper designs a system for national traditional sports video distribution with the help of software-defined network and mobile edge computing technologies. Thus, the popular national traditional sports resources can be cached in mobile edge computing servers, which can reduce the delay time from cloud center directly. In order to improve the hit rate of the cached videos, the ant colony-stimulated annealing is used as the caching strategy. The experimental results show that the ant colony-stimulated annealing caching strategy can increase the hit rate of the contents in mobile edge computing servers as well as decrease the delay time of the request videos. The ant colony-stimulated annealing caching strategy performs better than previous caching strategies for updating contents in mobile edge computing servers.
