Information-Theoretic Caching: The Multi-User Case

Michael Christoph Gastpar, Sung Hoon Lim, Chien-Yi Wang

In this paper, we consider a cache aided network in which each user is assumed to have individual caches, while upon users’ requests, an update message is sent through a common link to all users. First, we formulate a general information theoretic setting ...

A New Converse Bound for Coded Caching

Michael Christoph Gastpar, Sung Hoon Lim, Chien-Yi Wang

An information-theoretic lower bound is developed for the caching system studied by Maddah-Ali and Niesen. By comparing the proposed lower bound with the decentralized coded caching scheme of Maddah-Ali and Niesen, the optimal memory--rate tradeoff is char ...

Information-Theoretic Caching: Sequential Coding for Computing

Michael Christoph Gastpar, Sung Hoon Lim, Chien-Yi Wang

Under the paradigm of caching, partial data are delivered before the actual requests of users are known. In this paper, this problem is modeled as a canonical distributed source coding problem with side information, where the side information represents th ...
