Fundamental Limits of Shared-Cache Networks

Abstract : In the context of communication networks, the emergence of predictable content has brought to the fore the use of caching as a fundamental ingredient for handling the exponential growth in data volumes. This thesis aims at providing the fundamental limits of shared-cache networks where the communication to users is aided by a small set of caches. Our shared-cache model, not only captures heterogeneous wireless cellular networks, but it can also represent a model for users requesting multiple files simultaneously, and it can be used as a simple yet effective way to deal with the so-called subpacketization bottleneck of coded caching. Furthermore, we will also see how our techniques developed for caching networks can find application in the context of heterogeneous coded distributed computing.
