Coded Caching with Distributed Storage
Content delivery networks store information distributed across multiple servers, so as to balance the load and avoid unrecoverable losses in case of node or disk failures. Coded caching has been shown to be a useful technique which can reduce peak traffic rates by pre-fetching popular content at the end users and encoding transmissions so that different users can extract different information f...
متن کاملA Novel Centralized Strategy for Coded Caching with Non-uniform Demands
Despite significant progress in the caching literature concerning the worst case and uniform average case regimes, the algorithms for caching with nonuniform demands are still at a basic stage and mostly rely on simple grouping and memorysharing techniques. In this work we introduce a novel centralized caching strategy for caching with nonuniform file popularities. Our scheme allows for assigni...
متن کاملOn Coded Caching with Heterogeneous Distortion Requirements
This paper considers heterogeneous coded caching where the users have unequal distortion requirements. The server is connected to the users via an error-free multicast link and designs the users’ cache sizes subject to a total memory budget. In particular, in the placement phase, the server jointly designs the users’ cache sizes and the cache contents. To serve the users’ requests, in the deliv...
متن کاملCloud Radio Access Networks With Coded Caching
A cloud radio access network (C-RAN) is considered as a candidate to meet the expectations of higher data rate demands in wireless networks. In C-RAN, low energy base stations (BSs) are deployed over a small geography and are allowed to connect to the cloud via finite capacity backhaul links where the information is processed. A conventional C-RAN, however, requires high capacity backhaul links...
متن کاملOptimization of Heterogeneous Coded Caching
This paper aims to provide an optimization framework for coded caching that accounts for various heterogeneous aspects of practical systems. An optimization theoretic perspective on the seminal work on the fundamental limits of caching by Maddah Ali and Niesen is first developed, whereas it is proved that the coded caching scheme presented in that work is the optimal scheme among a large, non-t...
