Centralized caching in two-layer networks: Algorithms and limits


The problem of the centralized caching is studied in a two-layer network. The first layer of the network is constructed by a server and K<sub>1</sub> helpers, and the second layer consists of K<sub>1</sub> orthogonal sub-networks, each of which contains a helper and K<sub>2</sub> users. The pioneer caching design in the two-layer network is to directly… (More)
