ICN CACHE CAPACITY ALLOCATION METHOD BASED ON CLUSTERING
In order to reasonably allocate the cache space of each node in information-centric network(ICN),an ICN cache capacity allocation method based on clustering is proposed.After clustering the ICN nodes according to the node attribute data set,the obtained cluster center attribute data set was used to allocate cache space for each category.According to the Euclidean distance to evaluate the clustering effect,the cache space was allocated to each node in the category to improve the cache System performance.In practical applications,it can also provide certain guidance for internet service providers(ISP).The simulation results show that the proposed method improves the cache hit rate and significantly reduces the response latency compared with the equally distributed deployment method,the degree-based deployment method,and the betweenness-based deployment method.
