Caching refers to the act of replicating information at a faster (or closer) medium with the
purpose of improving performance. This deceptively simple idea has given rise to some of …

We consider the problem of proactive (ie predictive) content caching that is aware of the
costs of retention of the content in the cache. Prior work on caching (whether proactive or …

This paper aims to provide an optimization framework for coded caching that accounts for
various heterogeneous aspects of practical systems. An optimization theoretic perspective …

Caching is a technique to reduce peak traffic rates by prefetching popular content into
memories at the end users. Conventionally, these memories are used to deliver requested …

We study the optimal placement of content over a network of caches, a problem naturally
arising in several networking applications. Given a demand of content request rates and …

We consider a basic caching system, where a single server with a database of N files (eg,
movies) is connected to a set of K users through a shared bottleneck link. Each user has a …

This dissertation studies the replacement problem that arises in caching data objects of non-
uniform size. It assumes that the cache miss penalties are also non-uniform. It formulates the …

The design of caching algorithms to maximize hit probability has been extensively studied.
In this paper, we associate each content with a utility, which is a function of either the …

In this work, the peak rate of the caching problem is investigated, under the scenario that the
users are with small buffer sizes and the number of users is no less than the amount of files …

This paper has the following ambitious goal: to convince the reader that content caching is
an exciting research topic for the future communication systems and networks. Caching has …
